Specific Isotopes Flashcards
What enclosure of the BUMEDINST 6407.10 provides guidance for the isotopes
likely to be involved in a incident inside the Navy and the Marine Corps?
Enclosure 12
If there is a nuclear reactor accident, what is the prime nuclide of concern?
Iodine-131
What is potassium Iodide (KI)?
Medication used in radiation emergencies.
Why do we give out Potassium Iodide?
It saturates the thyroid gland with a stable Iodine thereby denying Iodine-131’s ability to cause a significant dose to the thyroid.
What are some side effects of Potassium Iodide?
- Skin rashes
- Swelling of salivary glands
- Metallic taste
- Burning mouth and throat
- Sore teeth and gums
- Upset stomach and Diarrhea
- Potential to cause anaphylaxis allergic reactions.
How is the issuance of KI documented?
Each individual issued KI, is given a SF-600 that is signed and dated, and placed in their health record.
What is the recommended dosage of KI for adults up to 40?
130mg/day when projected radiation dose to thyroid is 10 Rad or greater.
What is the recommended dosage of KI for adults over 40?
130mg/day when projected radiation dose to thyroid is 500 Rad or greater.
What is the recommended dosage for children age range of birth - 1 month?
16 mg/day when projected dose to thyroid is 5 rad or greater
What is the recommended dosage for children age range of 1 month - 3 years?
32 mg/day when projected dose to thyroid is 5 rad or greater
What is the recommended dosage for children age range of 3 years - 18 years?
65 mg/day when projected dose to thyroid is 5 rad or greater
How long should KI be given?
Until there is no significant risk of radionuclide.
The amount of KI to be maintained should be determined by what for ships and shore commands?
- For Ships, as defined in the AMAL list.
- For shore commands, based on the amount of emergency response personnel.
What is the expiration date of KI?
5 years after MFR date.
Where should the inventories of KI be documented?
Shelf Life Extension Program (SLEP).
Can expired Potassium Iodide tablets be used?
*Yes only in an emergency, as long as it shows does not show signs of degradation, fragmentation, or irregular services.
* The decision to do so, must be documented with the reasons why and REAB should be notified of the justification.
What are the isotopes of concern per BUMED 6470.10C?
- Chromium (Cr-51)
- Cobalt (Co-60)
- Iodine 131
- Depleted Uranium
- Plutonium (Pu-239)
- Radium (Ra-226)
- Tritium (H-3)
- Tech-99m
What class of medications are contraindicated by Chromium-51?
Antacids, because the increase the absorption of Ch-51 through the wall of the intestine.
How is the presence of internal contamination verified for Chromium-51 (Ch-51)?
(REVIEW)
Done by Vitro bioassay of urine and feces samples.
What are the therapy options for all the isotopes listed in enclosure 12 of the BUMEDINST 6470. 10C
- External, internal and wound Decontamination
What is the prime nuclide of concern for NNPP?
Cobalt-60 (Co-60)
Partial or whole-body counts must be obtained within 24 hours to help determine the presence of internal contamination and estimating the dose for what isotope?
Cobalt-60
What isotope targets bone surface, liver, and kidneys?
Depleted Uranium
Immediate gastric lavage is associated with isotope?
Radium-226
Depleted Uranium spent in contact with the skin delivers a skin dose of what?
Approximately 200 mRem/hr
What isotope targets the lungs, liver and bone surface?
Plutonium-239
What must be done within 30 minutes of plutonium-239 contact?
Use swabs to obtain a samples from the nose, throat and saliva.
If you have a sailor was exposed to Tritium (H-3) What will you do for their treatment?
- Collect urine samples within 2-24 hours post exposure
- Increase their fluid intake (2-4ml)
- perform Liquid Scintillation Analysis within 24 to 48 hours.
How would you treat a sailor who has been exposed to Cobalt-60?
Treatment them symptomatically if the external exposure is expected to be high enough to cause deterministic effects
What is the timeline of uptake for Iodine-131?
- 50% in the first 6 hours after the exposure
- 90% after 24 hours receipt of exposure
- Maximum uptake occurs 48 hours after exposure
What percentage of radium-226 is eliminated by urine and feces?
Feces is 95-98%
Urine is 2-5%
How often do you update the inventory record for potassium Iodide (KI)?
90 days
How long does it take for Cobalt 60 to transit through the GI tract?
Approximately 42 hours.
One uCi of Iodine produces a dose of what to the thyroid?
6.5 Rad/65 mrem
When personnel are exposed to radioiodine what administrative must be done?
Contact REAB so a f/u program can be recommended
How much of radium 226 is absorbed after ingestion?
Approximately 30%
Where is KI ordered from?
Defense Logistic Agency (DLA)
