Total Radiation Exposure

For 11/05-9/17:

1mSv = 100mrem

PET = 7mSv
CT = 10-12mSv (whole Body scan)
MUGA = 8mSv

Background radiation exposure in the US is ~3mSv/year.

A chest X-ray = 0.02mSv

1 CT = 500 x-rays
1 PET = 350 x-rays
1 MUGA = 400 x-rays

My Exposure Totals:
1 MUGA = 8mSv
4 PET scans = 28 mSv
9 CT scans = 90-108 mSv
Total = 126-144 mSv

Comparisons:
6300-7200 x-rays
42-48 years of background radiation

And counting.....
