disability resulting from such injury, and 2) medical treatment for such injury’. After a thorough study of all the factual and medical evidence submitted in your case, it has been determined that your skin condition was not caused by or aggravated by your working condition prior to 1966. There were no radiation programs in existence until 1960 at the . missile range; there were no known sourcesofradiation in your primary environment since February 22, 1959 when you were employed at {the army base} and your field work was administrative. ' Federal Employee's Compensation Act, 5 USC 8101, 8102 and 8103. CASE NO. 42 Type of Injury: Stromal Herpetic Keratitis and eventual loss of sight in one eye. BEC’s Decision: Compensation Denied. Date of Decision: 1970. Claimant's Allegation: That her eye condition is causally related to radioactive “spills” on two occasions during her employment. Facts: Claimant worked as technical editor and clerk typist in a government nuclear defense laboratory. Her desk and regular post-of-duty was in an anteroom outside of the actual laboratory where radioactive materials were handled. Records indicated that on November 13, 1961, 2 mg. Radium equivalent of Thorium 228 was moved into the laboratory in question. During experimental procedures on November 14, 1961, just before Iunchtime, a laboratory worker spilled approximately two micro-curies of Thorium 228, in solution, on the top of a stainless steel table. The spill was not discovered until right after lunch and the laboratory was ordered to suspend all routine operations. Monitors equipped with portable alpha survey meters were used to monitor all personnel prior to leaving the building. Claimant underwent such a check. She was not found to be contaminated with alpha particles. The monitors found one case of skin contamination. The left hand reading of the contaminated person was 250 c/m. All contamination was cleaned up promptly and claimant was not involved in the spill or cleanup operation. The laboratory resumed its regular work on December 19, 1961. A routine survey performed on that day revealed no removable contamination and external radiation levels of 0.03 mr/hr. On or about January 23, 1962 evidence indicates that one of the laboratory workers flushed a small quantity of “slurry” (wet waste) from a diamond cutting saw without realizing the material was radioactive and the sink trap became slightly contaminated. None of the slurry was spread about the laboratory and because there was no distributed contamination the incident was not treated as a “spill”. Unaware of the incident, the claimant entered the laboratory to get her coatwhich was on a coat rack near the work area. The next day the laboratory was closed and the sink was dismantled and cleaned before the laboratory resumed work. A survey record dated January 25, 1962 showed insignificant removal contamination. Fixed Thorium 228 was indicated in a hood containing the Thorium. Contact readings were 17 mr/hr. Readings in the office portion of the laboratory was 0.02 mr/hr. No other injuries of any kind were ever reported, even from persons much closer to the incidents than claimant had been. 130 13]
