He was treated for cerebral thrombosis in July 1966 and February 1967. On review, in April 1967, the agency of original jurisdiction held that entitlement had not been established to service connection for cerebral emboli with right hemiparesis, and confirmed the previous denial of service connection for arteriosclerotic heart disease. The veteran was duly informed in May 1967, including notification of his right to appeal. He replied that he wished to appeal. He stated that he believed he was entitled to service connection because all the doctors seemed to think that the blood condition he had had for 11 years could be due to the fact that about four or five weeks after the explosion he was in the area where the atomic bombfell. Medical Evidence: A statement from a medical doctor stated that the veteran apparently did well until the late fifties or earty sixties; that he had a generalized arterial disease that had manifested itself with coronary arteriosclerotic heart disease and had had repeated pulmonary emboli and recurrent thrombophlebitis; that a definite etiological factor had not been found to account for his symptoms; that it was within the realm of possibility that he could have some type of tropical fungus disease that he developed as a result of serving in the South Pacific; that he could well have developed some type of hematologic disorder secondary to exposure to the atomic bomb blast in Japan; and that it would be hard to prove, and even harder to disprove, that he had either a tropical fungus disease or that his hematologic disorder was related to the atomic bomb explosion. Findings of the BVA and Basis for Decision: In finding that there was no ae ee relationship between the veteran’s visit to Nagasaki or any other incident of service, and the development of generalized arterial disease many years after service the Board said: Under certain circumstances, radiation can induce leukemia. The veteran does not have leukemia. His heart disease is a result of atherosclerosis or arteriosclerosis. His hemiparesis is due either to the same process or to cerebral embolization caused by his vascular disease. There is no known relationship between radiation and vasculitis, Buerger’s disease, thrombophlebitis or atherosclerosis or arteriosclerosis. Furthermore, it is not shown that he was exposed to radiation during his visit to the Nagasaki bombsite more than a month after the blast, in an amount sufficient to have any deleterious effect on his health. Studies made by various scientific groups on the effects of atomic radiation have shown that the amount of radiation in the Nagasaki area was very slight. From the svailable information, it is most unlikely that the veteran received radiation of a harmful amount. The bleeding of his gums and other symptoms which he refers to as radiation symptomsare not shown to be such. ees The April 1967 determination by the originating agency that entitlement had not been established to service connection for arteriosclerotic heart disease and cerebral emboli with right hemiparesis is a final determination. (38 USC 4005) 106 CHAPTER fl DIGEST OF U.S. DEPARTMENT OF LABOR RADIATION CASES PART A BUREAU OF EMPLOYEES’ COMPENSATION CASES (Nos. 35 - 46) CASE NO. 35 Type of Injury: Chondrosarcomaofthe Pelvis. BEC's Decision: Compensation Granted. Date of Decision: 1969. Claimant's Allegation: That chondrosarcoma of the pelvis was caused by his exposure to X-radiation in the course of his employment. Facts: Claimant was a 44 year old medical radiology technician who worked in the radiotogy service of a government hospital for more than 18 years. His total time in such work was about 22 years. On March 19, 1965 the claimant complained of pain in the left hip and trochanteric area which allegedly had started about 2-1/2 years earlier and had gradually increased. X-rays taken showed a septic lesion. He was taken to surgery on March 29, 1965 and the lesion was excised. The pathological report was chondrosarcoma. Thereafter, he was examined at regular intervals. The tumor recurred and was again resected. In November 1966 & large mass immediately below the surgical incision was noted. In July 1967 an exploration of a pelvic tumor and obliteration of a mastive butee of the left hip, buttocks and thigh was performed. The employed..filed his claim with the Bureau of Employees’ Compensation on April 10, 1968. He died on April 27, 1968 and his widow pursued his claim. Records from the hospital ¢howed that the decedent was rotated through fluoroscopy, the radiographic room and dark room on a weekly change basis. In May 1949 a Keleket Dosimeter was used to measure X-radiation. No permanent records or readings were kept. Film badges came into use in October 1957. The film badge reports showed that decedent's total cumulative exposure from October 1957 to May 1967 was 420 milli-roentgens. However, evidence showed that the dosimeter was worn in the shirt pocket under a protective apron and the film badge was wom on the waist, right front, also 107
