My only real question is that if this is safe radiation, what amount constitutes "an entire lifetime's worth"?

If you are speaking of legal matters the Nuclear Regulatory Agency says this is safe for occupational exposure.

5 times your age minus 18 REM per year.

So if you are 20 that would be 2 times 5 which would equal 10 REM (Rad Equivalent Man).

Then the NRC defines the Lethal dose (LD) as:

The dose of radiation expected to cause death to 50 percent of an exposed population within 30 days (LD 50/30). Typically, the LD 50/30 is in the range from 400 to 450 rem (4 to 5 sieverts) received over a very short period.

So safe is probably somewhere in between.

Does that mean that if you get old enough you’re immune to radiation?
