What is a radiological incident ?
Above background from a legit source AND the source has NOT been released from its container
How would you confirm if you had a radiological emergency ?
Must be confirmed by a second meter
What is a radiological emergency ?
A source that is out of its container either accidentally or intentionally . Or where radiological meter readings are above what is expected for a specific location
When dealing with radiation what is the decision dose for life saving for a Catastrophic event?

10 rem
At a radiological incident what kind of decon are we gonna do?
Dry decon
If there is enough manpower to rotate members out of working area at a radiological incident this should be done when ?
At 5 rem dose levels or when 1 SCBA tank is expelled.
Dies every member that operates in a radiological emergency have to wear a dosimeter?
Yes
Can a thermal imaging camera be useful at a radiological incident?
Yes for life hazard and locating the dispersed radiological material
How long does the RAD 50 take for a change to come up on the screen?
One full minute
What is a safety factor in the rad 50 meter?
If the rate at any time exceeds 1 mr/ hr it will immediately sound the alert tone
When approaching a radioactive object or area how should you approach it?
In a circular pattern
What is FD action level at radiation events?
1 mr/hr
Where or what reading on a meter would the hot line get established?
2 mr/ hr
In a warm zone what other functions would you find there?
Decon
Safe area of refuge
When operating at a radiation incident and your dosimeter reads 5 rem what should you do?
Notify your officer and if enough manpower is available leave the hot zone
How many radiation detectors must each team have?
At least one
What is the priority order of decon at radiation emergencies ?
- Life threatening injuries
- Patients that are most severely exposed but are not symptomatic
- Discretion pregnant woman children seniors non life threat
What is the # class for radiation ?
7
