Did you forget your < /sarc > tag???

No, and I did not intend one, either.

Your body reacts *exactly* the same way to a radioactive particle as it would to a non-radioactive particle of the same chemical composition and physical structure. As for how the radiation itself affects the body, there are various caveats, such as what is the nature of the emission (beta, alpha, or gamma), what the energy of the emission is, and the quantity of radioactive material. Your body has redundant repair mechanisms for repairing damaged DNA, and a low dose exposure to radiation will not overwhelm those repair mechanisms. When those mechanisms are overwhelmed, the affected cells suicide (scientists call the process "programmed cell death" or "apoptosis"). At the point where cells are being overwhelmed is where the danger zone is: because not every cell with damaged DNA dies, and there is a higher chance of incorrect repairs when there is a lot of DNA damage. People who have this level of radiation exposure also have mild symptoms, like a sunburn. I won't get into what happens at higher doses of radiation exposure, since there is no reason to think that those 17 exposed sailors had even a minimally risky dose.

You might enjoy reading about the banana equivalent dose. Bananas carry radioactive potassium, which is spread throughout your body and incorporated into your cells whenever you eat a banana. I find the banana equivalent dose discussion a good overview of the issues of low-dose radiation exposure. Sometimes I joke that I haven't received my daily requirement of radiation, so I must eat a banana.

I don’t know you but I sincerely hope you are not involved in emergency management on the west coast or, for that matter, any other area subject to possible radiological emergencies.

I...am...without...words.
