1200 counts per minute (cpm) of contamination in wound.

Patient's response "No, I wasn’t ever nauseated."

Patient's response "I was outside."

Patient's response "Yes" to the question "Do you remember when the bomb exploded?"

Background radiation in the room is 35 cpm.

If contamination levels are not reduced by multiple cleansing attempts, it may indicate:

Internal contamination.

Aggressive scrubbing with Betadine® is needed.

Recent nuclear medicine testing.
