The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has released new guidelines for the protection of humans exposed to radiofrequency electromagnetic fields (RF EMFs). These cover exposures from a range of technologies, including existing 3G/4G and the upcoming 5G mobile telecommunications technologies, as well as DAB radio, WiFi, Bluetooth, radar, and wireless power transfer devices.
This is the first revision of the guidelines since 1998. Since then there has been an extensive scientific research effort to identify and better quantify potential adverse health effects resulting from exposure to radiofrequency EMFs. This has enabled a thorough update of the guidelines, with the result a protection system that can deal effectively with both contemporary and future technologies.
There are important changes to both the structure and restrictions of the new ICNIRP (2020) guidelines. Regarding structure, greater transparency should make the logic and scientific basis of the guidelines easier for the health protection community to engage with, additional means of assessing compliance with the guidelines have been provided, and there is now greater specification of how to assess complicated exposure scenarios.
Under the topic of restrictions, a number of additions and changes were made to ensure that the guidelines are not only protective for current radiofrequency EMF exposure scenarios but will continue to be protective for future technological developments. These include the addition of a restriction for exposure to the whole body for EMFs >6 GHz, to restrict body core temperature rise; the addition of a restriction for brief (less than six-minute) exposures to small regions of the body for EMFs >400 MHz, to restrict localised temperature rise; and the reduction of the maximum exposure permitted over a small region of the body for EMFs >6 GHz, again to restrict localised temperature rise.
The full guidelines are published in Health Physics ("Guidelines for Limiting Exposure to Electromagnetic Fields [100 kHz to 300 GHz]") and can be accessed at ICNIRP.org. Additional detail concerning the differences between the ICNIRP (2020) and ICNIRP (1998) guidelines is available on the ICNIRP website.

Eric Goldin, HPS President
First, I want to convey that the Health Physics Society (HPS) Board hopes you are all doing as best you can in these difficult days. And although the HPS annual meeting may not be foremost in your mind, we want to share our thoughts to answer some questions you might have about that meeting.
Bottom line: At this time, the Board is not cancelling the annual meeting. The situation is fluid and this decision will be reevaluated when the Board reconvenes on a conference call in mid-April. We will keep you updated.
Questions and Answers
Why aren't we deciding now?
As you know, hotels are in a bit of a bind with the numerous cancellations taking place, so they are taking a very conservative approach relative to cancellations that are more than a few weeks ahead. Since our meeting is in July, to cancel now would cost the Society $400,000.
Can we postpone?
We have looked into that. What we are finding is that if we can postpone to another date in 2020 (assuming the hotel has available dates), hotels are asking that the cost of the conference be paid up front to be used against the costs at the time the meeting is eventually held. The issue that comes up is around the new dates—if we cannot use them for some reason, we lose the money we paid, which would be the $400,000.
Do we have cancellation insurance?
Well … yes, but not to cover a pandemic. Even if there were domestic flight restrictions in place making it impossible to get to the meeting, if the restrictions are in place due to the pandemic and we have to cancel, we are not covered.
If the COVID-19 restrictions put in place by the federal government today are extended through July, could we cancel without a fee?
We do think that is possible. It is a waiting game. But it does appear that if the government has restrictions on gatherings that go as far out as July, we could cancel with little or no money lost.
Can we renegotiate the number of rooms we reserved or otherwise modify our contract?
Not at this time without fees.
Are we required to have a meeting?
Our Bylaws state that we are required to have one meeting each year. That actually is referring to a business meeting, not the regular meetings as we know them. And we could have a virtual business meeting at some point in the future if that becomes necessary to meet the requirements of our Bylaws.
What about meeting registration; shouldn't that be opening up about now? I don't know what my plans might be.
You are right that this is the usual time before an annual meeting that registration opens up. The Board decided to wait to open registration at this time because it makes no sense for our members to send in money for a meeting that might not be held.
In closing, we're sorry for any inconvenience we're causing you. Our thoughts and well-wishes are with each of you and your families. And again, we will keep you posted as we continue to evaluate holding the HPS annual meeting.

Did you know that the Health Physics Society (HPS) recruits member experts to answer radiation questions from members of the public? Ask the Experts (ATE) has become the most effective public outreach tool the HPS has. Gen Roessler started ATE back in 1999, and she was the National Council on Radiation Protection and Measurement's third Thomas S. Tenforde Lecturer. In her article (written with colleagues Kelly Classic and Fred Baes) HPS Ask the Experts: The Most Intriguing Questions and Answers in the April issue of Health Physics, Gen reports that over 13,000 questions have been answered and posted, and the ATE feature of the HPS website draws over a million visitors per year. I'm going to go out on a limb and assert without evidence that this makes ATE the most influential radiation-related public education tool in the world. What is the public asking about? Gen says the most frequent questions deal with medical exposures, especially computed tomography procedures, but the questions ATE receives cover a wide range of subjects, including "products from Japan, granite countertops, radon, smoke detectors, luggage and whole-body scanners, and radiation exposure from airline travel" and "exposure to nonionizing radiation sources such as cell phones, radar, ultraviolet radiation, lasers, and power lines." Gen's article also reveals the most intriguing ATE questions. Be sure to check out her fascinating article in the April issue of Health Physics!

Due to circumstances surrounding the novel coronavirus, COVID-19, the National Council on Radiation Protection and Measurements (NCRP) has cancelled the 2020 NCRP Annual Meeting, originally scheduled for 23–24 March at the Hyatt Bethesda Hotel in Bethesda, Maryland. In recent days, a number of speakers and council members have indicated that they will not be able to attend the meeting, with indications that others would reach similar decisions in coming days. The NCRP expresses its regret for the inconvenience.
The NCRP Annual Business Meeting will be held by webinar on Tuesday, 24 March, from 11 a.m. to 12:30 p.m. (Eastern). All council members will receive a separate email containing information about joining that webinar within the next few days.
All in-person PAC meetings scheduled for Sunday, 22 March, are also canceled. Either NCRP or PAC chairs will be contacting the members of their PACs with information on rescheduling PAC meetings to be held by webinars.
The scientific program that was arranged for the meeting—"Radiation & Flight: A Down-to-Earth Look at Risks"—will be carried forward to the 2021 meeting (19–20 April 2021 at the Hyatt Bethesda).
If the NCRP office made reservations at the Hyatt Hotel for you for the meeting, we will take care of canceling the hotel reservations. We understand that many airlines are allowing flight cancelations/changes without penalty at this time. Please inform us if you have any problems.
Mike Mahathy, HPS Director
In the January 2020 issue of Health Physics News, Brett Burk discussed copyright issues that the Health Physics Society (HPS) can encounter when publishing or posting your meeting presentation on the HPS website. A negative result of that is not being able to post meeting presentations on our website—a benefit many members have enjoyed.
This result is at odds with one of our strategic plan's priorities, which is to improve value to stakeholders. As a result, an annual priority work team has recommended the alternative to ask presenters to also upload a PDF copy of their presentation with all images removed, even those owned by the presenter or those for which the presenter has permission. This simplifies the process for posting and ensures we are compliant.
The Program Committee will ask each annual meeting presenter to provide the image-free copy as they review their presentation in the speaker ready room. Please note that this is voluntary; presenters will not be required to submit this second version, although we hope you will. Submitted presentations will be uploaded in accordance with HPS policies and time frames. The goal is to improve value of membership to our members.
In honor of Women's History Month, the Public Information Committee, in conjunction with the Women in Radiation Protection Section, has kicked off an effort to recognize the hard work and dedication of some notable women in the Health Physics Society (HPS).

We are four months from the Health Physics Society 65th Annual Meeting and, as we said last month, you can never begin to plan your visit to the National Capital Region too early. The week of 5 July will be bustling. This is what we've been working on to make your visit more enjoyable:
- The Pub Crawl is back this year! It will be held in Old Town Alexandria, and our transport vehicle will be the Potomac Riverboat Company water taxi.
- A tour to the SM-1 reactor located at Fort Belvoir is planned. We're still working on the details of a tour to Calvert Cliffs, and final arrangements will be announced shortly.
- Special events include a moonlight trolley tour of the national mall and the monuments, a salsa dance class, and a trip to the Nationals Park for a baseball game against the Saint Louis Cardinals.
Finally, the Baltimore Washington Chapter will take preorders on the polo shirts, t-shirts, and baseball caps. The logo is outstanding in red, white, and blue, celebrating July 4th on the National Mall.
Next month, we'll present more detail and provide information on shows, tours, and special events occurring over that entire week. For example, a look ahead—to make reservations for the newly renovated Washington Monument, tickets are available 90 days in advance at Recreation.gov. More secrets to come!

The Health Physics Society has published "Nuclear Power: Position Statement of the Health Physics Society" to support the position:
The Health Physics Society (HPS)* believes that nuclear power in the United States is a safe, reliable, low-carbon energy source. The exposures to radiation and/or radioactive material associated with nuclear power generation—and indeed the entire nuclear fuel cycle—have been effectively managed to ensure the safety of workers, the public, and the environment.
Thank you to Willie Harris and the Power Reactor Section for drafting the position statement that was approved by the Scientific and Public Issues Committee.
Isaf Al-Nabulsi, PhD, US Department of Energy
At the Health Physics Society (HPS) 65th Annual Meeting, which will be held at the National Harbor, Maryland, 5–9 July, a special technical session will be devoted to presentations and discussions of ongoing activities at the US Department of Energy (DOE) Office of Domestic and International Health Studies. Cochaired by Dr. Isaf Al-Nabulsi and Dr. Patricia R. Worthington, this session is scheduled for Wednesday, 8 July.
The Atomic Energy Act of 1957, Section 8(a) requires research and development activities relating to the protection of health during research and production activities. The requirement is fulfilled by supporting health studies and other research activities to determine if DOE workers and people living in communities near DOE sites are adversely affected by exposures to hazardous materials from DOE operations and to address critical research needs for important occupational exposures. The ultimate use of the information is to protect and promote the health of DOE workers, their families, and residents of neighboring communities and to share the information and data with the public.
The purpose of the international health studies and activities is to support the health and safety mission of DOE by providing new knowledge and information about the human response to ionizing radiation and other industrial exposures encountered in the workplace or within nearby communities. Activities are underway in Japan, the Marshall Islands, and the Russian Federation. These activities represent unique opportunities to enhance our knowledge and to establish science-based worker and public protection standards and to fulfill humanitarian purposes.
The goal of this session will be to increase awareness of ongoing health studies activities supported by the DOE. HPS members are invited and encouraged to attend the session. The invited speakers for the special session include:
- Terry Hamilton, Lawrence Livermore National Laboratory—Enewetak Atoll Resettlement: An Untold Story
- Sergei Y. Tolmachev, US Transuranium and Uranium Registries (USTUR)—US Transuranium and Uranium Registries: 2010–2020 Research Accomplishments and Collaborative Efforts
- Joey Zhou, DOE, and Martin Sefl, USTUR—Uncertainties in Radiation Dose Assessment for Internally Deposited Plutonium in Support of Radiation Epidemiology
- Maia Avtandilashvil, USTUR—Beryllium in the Tissues of Former Nuclear Workers
- Bruce Napier, Pacific Northwest National Laboratory—Recent Improvements in Dose Reconstructions for the JCCRER Russian Studies
- Dale Preston, Hirosoft International—Recent Findings on Cancer Risks and Chronic Radiation Exposure in the Mayak Worker and Techa River Cohorts
- Christopher Loffredo, Georgetown University—The Russian Human Radiobiological Tissue Repository: A Unique Resource for Studies of Plutonium-Exposed Workers
- Eric Grant, Radiation Effects Research Foundation (RERF)—Pilot Study: Dosimetric Impact of a New Computational Phantoms for the Japanese Atomic Bomb Survivors
- Kotaro Ozasa, RERF—Cancer Incidence Among Atomic Bomb Survivors in Hiroshima and Nagasaki
- Osamu Tanabe, RERF—Biorepository of A-Bomb Survivors and Their Offspring
- Sara Howard, Oak Ridge Associated Universities (ORAU)—A Treasure Trove of Radiation Monitoring Data: Review of the Department of Energy's Comprehensive Epidemiologic Data Resource (CEDR)

Health Physics Society member Dr. Alan Fellman is featured in Episode 3 of VersantCast, a podcast series hosted by Versant Medical Physics and Radiation Safety. Fellman and Dr. Eric Ramsay discuss the linear no-threshold (LNT) model, its history, and the increasing scientific evidence against the LNT model's efficacy. They also touch on the topic of sustainable and nuclear energy, radiation hormesis, and the shared hope for advancements in the health and medical physics community.
The 2020 Health Physics Society (HPS) Annual Meeting will be held 5–9 July in National Harbor, Maryland, at the Gaylord National Resort and Convention Center. Reservations can be made for either a deluxe guest room for $175 or an atrium view room for $215 (18% taxes additional). Rooms can be reserved at these rates between 3 July and 10 July so you can extend your stay before or after the meeting. Per diem rate rooms are available by calling the hotel directly and asking for the Health Physics Society conference per diem rate (phone: 301-965-4000).
Why should I book at the conference hotels?
The hotel rates that the HPS negotiated include many benefits for you and for the HPS. Based on the number of rooms in HPS block of hotel rooms, the hotels provide complimentary meeting room space, and reduced food and beverage charges. These savings are passed on to attendees through HPS inexpensive registration rates.
If HPS is unable to meet its room-block commitment because attendees are making reservations at other hotels, the hotels charge HPS an attrition fee to make up the hotel's lost revenue. If this were to become a trend, HPS would be forced to increase the registration fee and cut services.
Is it important for me to let the reservations agent know that I'm associated with the HPS meeting?
Yes. HPS receives credit only when registrants tell hotel staff that they are attending the HPS meeting. Please make sure the reservations agent knows you are attending the HPS meeting—whether you or someone else makes your reservation—or make your reservation through the link on the HPS site and it will be handled automatically.
Why does HPS reserve a block of rooms?
The HPS reserves a block of rooms to assure availability of rooms for meeting attendees, especially during the tourist season when it can be very difficult to find an affordable hotel room. If the HPS didn't reserve a block of rooms, we would be subject to room rental fees and full food and beverage costs, which would greatly increase the cost of holding the meeting.
What is HPS doing to reduce these attrition fees and still keep the meeting affordable?
HPS tracks sleeping room reservations and cancellations at the meeting so that it can more accurately block a number of rooms that will be filled by attendees in the future. However, every discount we receive at a hotel is based on the number of room nights we block, so as we reduce our block, we are consequently paying more for other services at the hotel. Reducing the block means attendees will either have to pay a higher registration fee or services will have to be cut.
Please stay at the HPS conference hotels!
HPS Local Arrangements Committee
The Baltimore Washington Chapter of the Health Physics Society (BWCHPS) was pleased to support local arrangements for the 2020 HPS Midyear Meeting, which was held in Bethesda, Maryland, the week of 19 January 2020. While there were many highlights of the meeting, we must say that there was great interest in the two tours that were arranged as well as the cool dry-fit HPS 2020 polo shirts that were offered for sale by the chapter and that will continue on sale through the annual meeting in National Harbor.
