- 0PGP03-ZR-0044 Contamination Control Program*
- *
What contamination levels are present in a contaminated area and a high contamination area?
- Contaminated Area:*
- *≥ 1,000 dpm/100cm2 beta/gamma**
≥ 20 dpm/100cm2 alpha
- High Contamination Area:*

≥ 1,000 dpm/100cm2 alpha
- 0PGP03-ZR-0050 Radiation Protection Program*
- *
What are the AAL radiation exposure limits?
- TEDE:*
- *2 R/year**
- Shallow Dose:*
- *40 R/year**
- Lifetime:*
- *N Rem (N=Age)**
No AAL for eyes b/c TEDE covers your eyes.

- *
If your total extended lifetime TEDE is extended past the limit, whose approval is required?
< 1 R Past Limit:
RP Manager

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>
- (Point Source Equation)*

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
