Answer to Question #6110 Submitted to "Ask the Experts"

Category: Historical Issues/Applications

The following question was answered by an expert in the appropriate field:

Q

I recently bought an item at a garage sale not knowing what it was. It is almost identical to the Zimmer Radon Generator featured on the Oak Ridge Associated Universities Web site with the exception that mine has inscribed on the bottom "Radium Emanator."

Is there any danger to me from handling this item? As soon as I read the bottom I became worried and put it aside. I handled it and the box it came in for about three to five minutes.

A

There is no "danger" associated with your handling of this item, but it is not something that you want to keep. Just as it is unwise to have unused chemicals (for example, paint solvents) in the house, it is best not to have radioactive sources even if they do not pose a hazard in their present condition.

The one shown on the Oak Ridge Associated Universities Web site has had the radium source removed and properly disposed of. Do not try this yourself; opening of the device and removal of the radium source is an operation that should be conducted with great care by qualified persons to ensure that there are no "surprises" such as contamination or other radiation hazards.

Your first step should be to contact your state radiation control program. One of its functions is to assist in these kinds of matters. Contact information can be found at the Oak Ridge Associated Universities Web site or the Conference of Radiation Control Program Directors Web site.

In the meantime, just seal it in a plastic bag.
