TBM

Question 1

8 parts of the tool

Answer 1

• Digital display shows either mR/h, or Dose
• Select (SEL) and reset (RST) buttons
• LED lights
• Volume control knob
• 3 position switch: ON/OFF/BAT
• Powered by 6 AA batteries (Approx. 100 hours
  use)
• Swivel type handle
• Detector protected by a plastic slide cover

Question 2

What is it used to detect

Answer 2

Use to detect Alpha, Beta, and Gamma radiation on explosions, rad occupancy or
CBRNE calls

Question 3

2 maintenance parts

Answer 3

• Check Batteries and replace as necessary.
• To protect detector, keep plastic cover over detector window when storing

Question 4

10 parts of use

Answer 4

• Check battery: switch to BAT position. Green “BAT OK” LED should illuminate.
• Turn on, open slide cover and ensure detector is in Rate Mode (“R” shows on digital
  display).
• To alternate between Rate and Dose modes press SEL button.
• To reset dose- press RST button in either mode.
• Adjust volume.
• Screen surface or patient: 1” away, 1”/sec, 2 min/pt.
• Normal background radiation is = 0.02 mR/h
• Contamination is ≥ 0.04 mR/h
• Warm zone is established at 2 mR/h up to 10 mR/h.
  o Back out and notify command or HazMat.
• Determine presence of Gamma by closing slide cover. Gamma will pass through
  slide cover and/or detector.
  o If reading drops considerably or totally, it is probably Alpha or low-level Beta

Question 5

where is warm zone established? What do you do?

Answer 5

2 mR/h up to 10 mR/h. Notify command or Hazmat

Question 6

o If reading drops considerably or totally, it is probably

Answer 6

Alpha or low level beta

Question 7

Three safety factors

Answer 7

• Turn on and lower plastic cover prior to or immediately upon responding to any
  explosion, unusual fire or suspicious event.
• Use proper PPE to avoid exposure.
• Remember the principles of protection from radiation:
  o TIME
  o DISTANCE
  o SHIELDING

Question 8

3 principles of protection from radiation

Answer 8

time, distance, shielding
