State the rule of eights.
|
Co-60. If inhaled 80% of the isotopes are eliminated with a biological half-life of 1 day or less.
-2/8 is exhaled -5/8 is trapped in mucous membranes then coughed up and swalled then passed through GI tract -1/8 eliminated more slowly. |
|
|
Identify and describe the four ways personnel may be exposed to ionizing radiation IAW BUMEDINST 6470.10B.
|
1) External Irradiation- exposure that originates external to and usually not in contact with the body.
2) External Contamination- If body contains in excess of 450uuCi/direct frisk or 50uuCi/direct frisk. 3) Wound Contamination- Radioactive material present inside or at the border of a break in the skin. 4) Internal Contamination- When radioactive material has gained access to the body through ingestion, inhalation, absorbtion or impingement. |
|

|
|
What methods are available to detect wound contamination for alpha and beta/gamma?
|
