How you determine the dose rate received from a point source and a line source?
- Point Source:*
- *DR1(D1)2 = DR2(D2)2**
- Line Source:*
- *< L/2 → DR1(D1) = DR2(D2)**
- *> L/2 → DR1(D1)2 = DR2(D2)**<strong>2</strong>

What must be done if a woman declares herself pregnant?
Restrict RCA Access
Issue new TLD
Figure out dose since conception
Woman, HR, and RP manager agree on new limit
Limit is < 450 mrem/pregnancy
If ≥ 450 mrem since conception, then limit is 50 mrem for the rest of the pregnancy.
Note:
NRC limit is 500 mrem/pregnancy
