As an employee in the nuclear industry I am sensitive to news item about the effects of radiation. The effects of low levels of radiation have always been difficult to determine because they are so much smaller than other things we do to ourselves. This article reports that the statistics show that low level radiation may actually be beneficial. One should make sure that the apparent benefits are not caused by secondary activities. For example, the health regulations in my industry call for more frequent and more thorough medical checkups than for most other workers. This could explain better longevity stats if serious illnesses get detected earlier.
