Conversation so far:
What is important to know about the radiation dosage?
The radiation doses received in these two accidents are not known with any semblance of accuracy.
A large part of the dose was due to neutron radiation.
Anything else pertinent to the dosage?
A "tentative" estimate of the doses involved was made in 1948, based on dozens of assumptions, some of which are now known to be grossly incorrect.
Any treatment or cure?
CANNOTANSWER.

Question: Are there acceptable dosages?
Self-contained rewrite: Are there acceptable dosages of radiation?
