Aradiation worker is subject to a dose of 177 mrad/h of 8.4 quality factor neutrons for one 40 h work week. how many times the yearly allowable effective dose did she receive? the allowable yearly effective dose for a radiation worker is 5.00 rem.

The allowable yearly effective radiation dose of a worker is 11.89 rad/yr

Given:

Rate of radiation dose a worker is subjected to, r = 177 mrad/h = 0.177 rad/h

time taken, t = 40 h

quality factor, Q = 8.4

allowable yearly effective effective dose = 5.00 rem

Solution:

Effective radiation dose can be calculated as a product of radiation rate, quality factor and time taken.

Now, calculating effective dose of radiation, as:

= 59.47 rad/h

Now, for allowable yearly effective dose of radiation, R:

R =  

R =  

when it gains or loses electrons
