haled or ingected material and the blownedical aspects of the incident
have been discissed in other CASTLE Project ll reports,
It was coneluded that: (1) the aN/PER-J9Aa Poquires a correction
factor of about plus 20 percent in dose-rate readings made unier the

believed expressible by the factor of que 3; (3) the evternal ganna

1500 kev; (4) the beta dose was delivered by beta radiation of mascLuum
energias of 0,3 and 1,3 Mev, mostly tron fallout ceposited on the skin
