Radiation Protection Drug

Here is an article that describes a new medication that protects people are exposed from lethal doses of radiation.

I'm a little skeptical about this news. It is hard for me to understand how you can use a drug that somehow overcomes biological molecules being ripped apart due to ionizing radiation passing through a cell. Radiation breaks chemical bonds and creates free radicals. You can neutralize free radicals (good example is eating fruits and vegetables high in antioxidants which helps the body repair damaged DNA) in some cases, but it would seem to be difficult to put 'Humpty Dumpty' back together when it comes to dealing with an original molecule other than DNA.

The article doesn't give a lot of detail, but we'll see what shakes out over the next few weeks.
