Hospital Xrays/CAT scans hit you with 10-20 milliSieverts of total exposure (1/1000 of a Sievert or mSv). This is about 3-7 years of normal background rad exposure. (40 CAT scans get you in the realm of a Chernobyl plant worker).

Commercial pilots flying 700 hr/year normally get about 2 mSv exposure total.

The event this morning was about 10,000 times higher than normal background radiation. So roughly this morning's dose was probably about what they would get in a half or full year depending on a lot of factors ... still less than a single hospital xray in total.

The key thing is that rad exposure comes down to total dosages received over a lifetime. Ionizing radiation is hard on DNA/immune systems. Less is better.
