16
Q

What is the lethal radiation dose for 50% of the population without medical treatment, with medical treatment?

A

w/o: 300-400R

w/: 600R

17
Q

What are the basic principles of ALARA?

A

as low as reasonably achievable (ALARA)

  • maximum distance
  • minimize exposure time
  • maximize shielding
18
Q

If there is need for extended operations in a radiation field what is one way to reduce each person’s exposure?

A

rotating personnel

19
Q

What should personnel always wear on a radiation event?

A

-Structural PPE including SCBA

20
Q

Dose limits (radiation) per activity?

A

5R: all activities
10R: protecting major property
25R: lifesaving or protection of large populations
>25R: lifesaving or protection of large populations; only by volunteers who understand the risks

21
Q

What is the most dangerous type of radiological exposure to the body?

A

inhalation, wearing SCBA affords the greatest protection for all firefighters in any WMD event

22
Q

If you are responding to an event with numerous people down every effort should be made to approach the incident from?

A

uphill and upwind; additionally, begin the approach 500’ from the incident or at the edge of the debris field

23
Q

If a firefighter runs out of air what can be done to minimize inhalation of radioactive materials?

A
  • do not remove face piece, improvise by covering face piece regulator hole with something that has not been contaminated
  • at a minimum, cover hole with a glove or hood until emergency decon can be done
24
Q

If initial FD personnel are not equipped with radiological dosimeters how long may they conduct life saving operations?

A

15 min

25
Q

What takes precedence, treatment of life-threatening injuries or decon?

A

treatment

26
Q

When treating contaminated pt’s personnel must wear?

A

Respiratory protection, at a min. surgical mask, gloves, and gown. FF PPE or Level C ensemble is recommended

27
Q

If no victims are present on a WMD incident actions should be limited to:

A
  • Establish a control zone
  • Isolate the area
  • Evacuate the area
  • Deny entry
  • Establish staging area for incoming units
  • Establish extended action plan
28
Q

Maximum Zone Limits for RDD with Life Safety?

A

Cold Zone: 2 mR/hr
Warm Zone: 2mR-10R/hr
Hot Zone: Over 10R/hr
Absolute Turn Back: 200 R/hr

29
Q

When creating hot/warm/cold zones for a radiological event will they typically be in concentric circles?

A

not likely

30
Q

For the cold zone the 2mR/hr line should only be used when there is no contamination present within the cold zone, if contamination is present the cold zone line should be pushed back to levels consistent with:

A

two times background or 50uR/hr

31
Q

When wearing external dosimeters they should be read and reported every?

A

15 minutes
