Answer to Question #4575 Submitted to "Ask the Experts"

Category: Radiation Effects — Low-Dose Effects

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

Q

Should a person be concerned with a dose of 1,082 mrem from fallout? I was a participant in Operation Hardtack, 1957-1958, at Enewetak Atoll. The Department of Energy, National Nuclear Security Administration Nevada Site Office, sent a radiation exposure history that reported that my whole-body gamma dose was 1,082 mrem.

A

There is no reason for concern about the radiation dose you received nearly 50 years ago. You have received a dose of about 300 mrem per year all of your life from natural (not man-made) environmental radiation. So your dose from fallout is a small fraction of your total dose. There is no conclusive evidence that such doses are even harmful.
