Answer to Question #368 Submitted to "Ask the Experts"

Category: Radiation Effects — Effects on Materials

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

Q

I was wondering if you could answer a little question for me . . . I install video surveillance systems and have been asked to quote a job which involves putting a camera in the same room as the cobalt used for irradiating imported products and sterilizing surgery equipment. I have been warned that once the cobalt is exposed (out of the water tank) it will turn all glass black (e.g., camera lens), rendering the camera useless. Is there any material that cobalt won't affect (e.g., plastics) but that the camera could potentially "see" through?

Thanks in advance.

A

Our best advice is to suggest that you contact a company that manufactures or sells video surveillance cameras. One that we are familiar with is Thermo Scientific. You may wish to visit the company's Web site.
