Very well founded post.

As emergency workers, we carry personal dosimeters in a disaster scenario. The dose limit per year is 200 millisieverts (mSv), which translates to about half a chest X-ray. For actual disasters, we've agreed on a dose of two sieverts, which (statistically speaking) causes rad poisoning in 2.something percent of healthy individuals if said radiation is absorbed within ten minutes. This is of course only if human lives are in danger. Otherwise, we foam the hell out of the area (to keep dust down), keep people away, and wait until the radiation either dies down or until the Army shows up.

Our protective suits are standard hazmat suits. They offer very little beta-, and no gamma- or neutron radiation protection, but a quick high-pressure was cleans them nicely, so you can get out of the suit in relative safety. Actual danger is minimal, the digital dosimeters have various alarm limits so we can leg it in time if we have to.
