1

The NCR's (National Capitol Region) fire departments will use the _____________ as the standard unit to mesure radiological exposure.

Roentgen (R)

2

Radiation exposure rates will be mesured in Micro-Roentgen (uR), _______________ and _____________, per hour

Milli-Roentgen (mR) and Roentgen (R)

3

If 1,000 (uR) = 1 (mR) and 1,000 (mR) = 1 (R) Then 1,000,000 (uR) = ___?

1 (R)

4

What is the natural background of radiation in DC?

5-20 (uR) per/hr or 0.005-0.2(mR) per/hr

5

What does ALARA stand for?

As Low As Reasonably Achievable

6

What are the basic priciples for ALARA?

Maximize distance, Minimize exposure, Maximize shielding

7

What is the Dose Limit (whole body) for- All Activities?

5 (R)

8

What is the Dose Limit (whole body) for- Protecting Major Property?

10 (R)

9

What is the Dose Limit (whole body) for- Lifesaving or protection of large populations?

25 (R)

10

What is the Dose Limit (whole body) for- Lifesaving or protection of large populations, Only by volunteers who understand the risk?

>25 (R)

11

Where should the "Control Line" be established on incidents without life safety concerns?

2 times normal background or 50 (uR)

12

What would you find in the "Cold Zone"?

generally an area intended to act as a buffer to keep persons not involved in the response away from the incident at a safe distance- Max Limit for this zone is 2 (mR)

13

What would you find in the "Warm Zone"?

decon, equipment- Max Limit for this zone is 2(mR) to 1 (R)

14

What would you find in the "Hot Zone"?

greatest degree of threat, highest level of ppe, clearly marked with tape to represent the greatest level of personal protection. This area is over 1 (R)

15

What is the "Absolute Turn Back" Exposure?

200 (R)

16

What do Dosimeters record?

Total exposure to external gamma radiation

17

Where shoud "Pencil Dosimeters" be worn

Outside of PPE, on the core of the body, to allow for reading in the hot zone. these readings should be given every 15 minutes
