REPORT OF =XCiSS PERSONNEL RADIATION DOSAGE, SA-16 AIRCRAFT 1. PURPOSE: To collect all information available relative to radiation dosages received by personnel aboard SA-16 Number 51-016 on 1 November 1952. 2. NARRATIVE: The SA-16 Aircraft was orbiting a positing in the area of the "Control" B-29 on day of mission. At approximately 1019 local time, this Rescue Aircraft was ordered to perform an interception of two Fighter Aircraft running low on fuel. While executing the intercertion, the SA-16 flew throughradioactive clouds with peak readings of 17 Roentgens. One Jet Fighter Aircraft subsequently landed in water three and four tenths (2 4/16) miles short of Eniwetok. The pilot is missing and presumed to be a fatality. This SA-16 Rescue Aircraft was within approximately one mile of the jet fighter at the time of ditching. The SA-16 continued searching the area until approximately 1258 local time and then landed at Eniwetok to refuel the aircraft. The aircraft was met by a Radsafe Monitor on the ground at Eniwetok who informed the erew that their aircraft was "HOT". The crew rerlied with the answer that they were aware of the fact. Brigadier General Glantzberg also met the SA-16 crew. He remarked to the crew that there was a possibility of "Fall-out at Iniwetok". General Glantzberg was not aware of the intensity of Radiation received by the SA.16 Crew. 3. FINDINGS: a. The radiation limit as established by JTF at time of this mission was 3.0 Roentgens. A subsequent message amended the limit to 3.9 Roentgens. This total integrated permissible dose covers a three month operational period. b. Personnel of this crew received from 10 Roentgens to 17.8 Roentgens. c. The Radsafe Monitor on this crew had a one week course in Radio- d. The aircraft first entered radioactive clouds at aprroxima:ely logical training. 2 1019 or shortly thereafter and did not arrive at Kwajalein until 1700, The crew was exposed to varying amounts of radiation aprroximately 6 hours and 30 minutes.
