SOG HAZ MAT 004 RESPONSE TO RADIOLOGICAL EMERGENCIES Flashcards
Typical radiological sources that are non-criminal in nature stem from where?
Medical offices or laboratories
The city of New Haven serves as the host community for which plant?
Millstone III-these incidents have a separate response plan
How do radioactive materials give off energy?
Rays and particles
How do radioactive rays and particles cause harm?
They can damage tissue
What does the amount of tissue damage depend on?
Length of exposure and distance from the source
What are the 3 natural defenses against radiation?
Time
Distance
Shielding
What are the 3 forms that radioactive sources can be found in?
Solids
Liquids
Gases
What is the best protection against internal radiation?
SCBA to prevent inhalation hazards
What is secondary contamination?
Radioactive dusts and liquids adhering to other objects such as clothing, tools, equipment, apparatus, smoke
What amount of protection does firefighting PPE provide from radioactive material
Limited protection
Who should be consulted regarding instructions and guidance with radioactive materials?
Radiological plant supervisor/personnel
When firefighting is needed with radioactive material, what is the best method?
Dry chemical extinguishers when possible
If water has to be used on radioactive materials, what method should be used?
Fog pattern only, low velocity fog, unless ordered otherwise by chief officer in charge
What should be avoiding with water?
Accumulation of water into puddles
How far should all non-emergency personnel and vehicles be kept from a scene?
At least 500ft
How do radioactive scenes need to be approached?
With meters on and personal dosimeter in place
When should radioactive areas not be entered?
> 100mR/hr, unless it is necessary to treat injured personnel or prevent the spread of contamination
A controlled area for personnel must be set up how far from the scene?
At least 100 feet from the scene
Exposure levels in uncontrolled areas must be less than what level mR/hr?
<2mR/hr
What should be done with radioactive material?
Do not move or handle it, cover or contain the material to prevent further spreading
What should be established at the entrance and exits of the scene?
Control points, to be manned at all times
What readings are considered contamination of clothing and equipment?
100cpm(counts per minute) >background or greater when measured with a geiger or ludlum with “pancake” detector
What information needs to be obtained from individuals entering the control area?
SSN, address and survey results
