What Enclosure of the 10C provides guidance to commands on supplies for personnel decontamination?
Enclosure 13
Four Methods of exposure
- External Irradiation
- External Contamination
- Internal Contamination
- Wound Contamination
What is the primary objective of skin decontamination?
Prevent Internal contamination through ingestion or inhalation.
What are approved methods for external wound decontamination? (CHECK TO SEE IF THIS APPLIES TO NONWOUND)
- Soap & Water
- Waterless hand cleaner
- Taping
- mild abrasive soap and water
- Sweating/skin sloughing
What entity do you receive guidance for responding services that may be to a radiological casualty?
BUMED Radiation Effects Advisory Board.
NAVMED 6470/18
Personnel monitoring and decontamination
NAVMED 6470/19
Detailed Personnel Monitoring Survey
NAVMED 6470/20
Detailed Face Monitoring Survey
NAVMED 6470/21
Detailed Hand Monitoring Survey
NAVMED 6470/22
General Contamination, Radiation, and Airborne
What is the order of priority for external contamination?
- Remove the clothes
- Decontamination any contaminated open cuts or wounds
- Decontamination external and external areas of the face
- Decontamination front and back of hands
- Decontamination all other contaminated areas of the body.
You should immediately contact REAB if an estimated internal contamination dose exceeds what limit?
50 rem to any organ or 5 rem whole body in a single incident.
What the stages associated with ARS?
- Prodromal
- Latent
- Manifest Illness
- Recovery or Death
What are the classes of ARS?
- Hematopoietic/Bone Marrow Syndrome
- GI Syndrome
- CV/CNS Syndrome
What are some considerations for external skin contamination?
- What is the extent of contamination on the skin?
- Is it there a chance internal contamination?
- Are there any clinical s/s expected?
- Is this an acute health problem?
What is the main objective of external decontamination?
- Prevent internal contamination from ingestion and inhalation
- Minimize the dose to the eyes and skin
How do you evaluate for internal contamination?
Gather data to estimate the amount of the contamination and expected dose from the following;
* Nasal swabs
* Throat swabs
* Saliva swabs
* Internal monitoring
* Compare estimated intake to DAC and ALI values
In accordance to what, will you report and document the occurrence of internal contamination?
Chapter 5 of the P-5055.
How do you evaluate external contamination?
- Treat Life, limb, eyesight first
- evaluate the extend of the external contamination and the possibility of internal contamination
- Gather a hx from the patient and witnesses to document the events leading up.
If external irradiation exceeds federal exposure limits, what shall be done?
- Contact REAB and a submit a report with measured/estimated dose within 24 hours
- Conduct a SE RME
- Bio-dosimetry dose calculations
- Document the determined dose on a NAVMED 6470/1 and submit to NDC and REAB within 30 days of exposure
An individual survival for external irradiation should not be question unless
- Dose to body exceeds 200 Rad
- Dose to a major segment of the body e.g. head or thoracic region is several hundred to thousands rad.
- Combination of serious physical injury and dose
Four Cs of high neutron exposure
- Collect 10ml of blood and 100ml of urine
- Collect 1/2 gram of hair
- Collect any metal objects the individual wore during exposure and document
- Consult BUMED REAB
Neutron exposure greater than ___ should initiate the 4Cs
25 Rad
How long do you slough a wound?
6 to 9 hours.
How does internal contamation occur?
Via
* Inhalation
* Ingestion
* Absorption
* Wound
Survivability is questionable at what whole body deep does rate?
350-400 Rad
What timeframe for soap and water, waterless, hand cleaner, and mild abrasive soap, and water?
1-3 minutes
What enclosure provides information and guidance for isotopes likely to be involved in an incident in the Navy and the Marines Corps?
Enclosure 12
What is LD 50/60?
50% of a exposed population will die within 60 days w/o medical treatment
What is the detectable count for Alpha emitters?
50 uuCi/direct frisk
What is the dectable count for beta-gamma emitters?
100 CCPM or 450 uuCi/Direct frisk
What is used for beta/gamma monitoring?
IM-271 w/ 304 Probe
What is used for Alpha monitoring?
MFR w/ DT 681 probe
An effective decon attempt is marked by what?
Reduction of survey count by 50% or more
