Findings of the ECAR: \n affirming the Bureau's denial the Board stated: The medical evidence submitted since its prior review does not cannot be ruled out, particularly with respect to total body count findings, persistent borderline leukocyte and platelet counts, and perhaps the poor wound healing”. establish any compensable disability due to appeliant’s employment-related exposure to radiation. The reports by the two radiologists, together with medical evidence previously in the record, BEC subsequently referred appellant, with the case record and a statement of accepted facts, to a Board-certified radiologist, for an examination and opinion regarding causal relation between appellant’s exposure to ionizing establish that the right hand condition is not causally related to the radiation exposure and that appellant does not have any employment-related disability. radiation and the delayed healing of his hand. He wasalso asked to express an opinion as to whether appelfant’s other disabling conditions were caused or adversely affected by his employment-related radiation exposure. He examined appellant on January 3, 1968. He pointed out that there was “no evidence of tadiation change as evidenced by atrophy, hair loss or telangiectasia in the skin of either lower extremity, of the left hand, the visible remaining right fingers, or in the mucous membranes of the oral cavity’ and he further stated that because of the short range of beta rays given off by strontium 90, any injury caused by such radiation would have been to the most superficial tissues, that is, the skin, that skin healing had not been a problem after the injury to the tight index finger, that a review of the contemporaneous medical notes indicated that healing of the finger progressed normally but that osteomyelitis, perhaps complicated by a foreign body, had perpetuated infection and required amputation, and that the norma! white blood count at the time of the finger injury and the lack of any increase in pulmonary infections secondary to appellant’s preexisting chronic pulmonary condition indicated that the exposure to radiation had not resulted in a depression of his body defenses to infection. He concluded that the right arm disability due to causaigia and loss of function from disease was not causally related to the radiation exposure. He also negated causal relation between the radiation exposure and appellant's cardiac and cerebral vascular disease, dermatological findings, bilateral cataracts and chronic pulmonary condition. To further assist in resolving the question of causal relation, the BEC referred appellant, with the case record and the statement of accepted facts, to another Board-certified radiotogist, who examined him on July 2, 1968. The radiologist had blood and bone marrow tests made, which were nondiagnostic. A consultant in dermatology also reported that the skin lesion on the left leg was typical of localized neurodermatitis and that the nose Jesion appeared to be an actinic keratosis. The radiologist reported, after a careful study of the case history, that the radiation exposure was only 10 percent of the permissible meximum and that this was insufficient to result in decreased resistance to infection. He stated that the healing of the primary infection of the right index finger was ogmplicated by a secondary infection involving the tendon sheaths. He negated causal relation between the radiation exposure and the infection of the right index finger, pointing out that the bone marrow studies had excluded the possibility of disease in the bone marrow or blood forming organs. He: stated that the only disability which could possibly have been caused by radiation would have been the leg skin lesions, but that those lesions did not have the characteristics of radiation dermatitis. The doctor concluded that appellant did not have any disability causally related to his exposure to radiation in his work. BEC medical advisers concurred in the opinions of the two radiologists, and the BEC denied modification ofits earlier decision. 1St 150 [linia ee _- do
