36
Q

Operations at a radiological incident

A

Confirm initial readings with a second meter

The thermal imaging usefully tool by assisting in search of victims as well as the dispersal device

39
Q

It takes about a minute for the rad-50 to India re a change on the LCD screen as a safety feature the rad-50 will alarm if the rate exceeds ___ at any time

A

1mR/hr

40
Q

When approaching a object how should you approach the object when using the rad50 to establish the hot zone

A

Circular pattern

Hot zone at 2mR/hr (Canberra alarms )

41
Q

Hot zone a radiological emergencyn

A

Hotline is the edge of the hot zone after which no contamination is present area is cold
Greater the 2mR/hr is hot zone

Hot zone is restricted to rescue and fire suppression
Hot zone may be expanded at
Castrophic event

42
Q

Warm zone at a radiological emergency

A

Does not encircle the source of radiation
Specific area near the edge of hotline usually superimposed in the cold zone
Established if contamination present and decon needs to be implemented

A

Less Than or equal Twice background .10mR/hr

If using the pancake probe on Ludlum it will be 50-200 cpm

45
Q

Priorityn of decon at radiological

A

Will depend on the location of the decon , extent of decon as well as the nature of person injuries
1. Patients with life saving injuries ( injuries that effect ABCS )
2. Patients that are most severely contaminated but are not symptomatic
