We review some of the claims and research in regard to yeast derived Beta Glucan protecting lab animals from lethal doses of radiation.

Beta Glucan appears to show incredible promise, ( at least in a lab setting ) in enhancing animal survival in extreme radiation events up to 11 gray. ( 3 gray normally is lethal to humans )

For further comparison these are in milliGray:
“The average radiation dose from an abdominal X-ray is 0.7 mGy, that from an abdominal CT scan is 8.0 mGy, that from a pelvic CT scan is 6 mGy, and that from a selective CT scan of the abdomen and the pelvis is 14 mGy.”
