Question

Dosimetry Problem A radiation worker is subject to a dose of 100 mrad/h of protons for one 40 h work week. How many times the yearly allowable effective dose did she receive? HINT: To obtain the effective dose, multiply the dose rate by the time in hours and the guality factor. You then have to divide this by the allowed dose for a radiation worker per year.

So it should be 50 10~(-3)*40/s

Explanation / Answer

given dose 100 mrad/h

QF for proton is 1

Total dose = 100 mrad *1*40 hour/week *52week = 208000 m rad = 208 rad

so 208 rad/1year = 208 rad/year
