Which acute radiation subsyndrome is typically associated with whole-body doses above roughly 6 Gy and presents with severe diarrhea and fluid loss?
Answer: Gastrointestinal
High doses destroy intestinal crypt cells, causing GI syndrome with fluid and electrolyte loss.
Doses above roughly 20 Gy typically produce which syndrome, with a very poor prognosis?
Answer: Neurovascular (cerebrovascular)
Very high doses cause neurovascular collapse with seizures, hypotension, and death within days.
How does increasing whole-body dose affect the latent period of ARS?
Answer: It shortens it
Higher doses shorten the symptom-free latent period and bring forward the manifest illness.
When a patient has both contaminated wounds and intact skin contamination, which should be decontaminated first?
Answer: Wounds
Wounds are decontaminated first, since they can allow internal uptake, and are then covered before intact skin is cleaned.
Which agent is a cytokine used to support recovery in hematopoietic ARS?
Answer: Filgrastim (G-CSF)
G-CSF stimulates neutrophil production and is recommended for significant marrow suppression.
A person who was externally irradiated by a distant source, but has no contamination, poses what risk to rescuers?
Answer: No radiation risk
External irradiation does not make a person radioactive, so they can be treated safely.
Under EPA guidance, what dose guideline applies to emergency workers performing lifesaving activities?
Answer: 250 mSv (25 rem)
EPA PAGs allow up to 250 mSv (25 rem) for lifesaving or protection of large populations, on a voluntary basis.
