Orville Kuehner, born in 1911, retired in 1978 from his job as a repairman for a coal *440 mining company. He had been employed by Ziegler Coal Co. for almost 40 years, three underground and 37 on the surface. Kuehner applied for benefits under the Black Lung Benefits Act, 30 U.S.C. § 901-45. He is entitled to benefits if he is totally disabled by pneumoconiosis.
According to the administrative law judge, x-rays establish that Kuehner has simple pneumoconiosis. This, coupled with Kuehner’s employment in a coal mine for more than 10 years, creates a presumption of total disability. 20 C.F.R. 727.203(a). The presumption may be rebutted. See
Amax Coal Co. v. Director, OWCP,
The physicians based their views on exercise tests (one made Kuehner walk quickly up a hall and ride an exercise bicycle), on pulmonary function studies (measures of how much air the person’s lungs can handle), on blood gas studies (measures of how much oxygen the blood carries), and on available x-ray films. Kuehner argues that because the physicians, and so the administrative tribunals, considered the same sorts of evidence that gave rise to the presumption of total disability, their conclusions do not supply substantial evidence to rebut the presumption. For a time the Fourth Circuit took such an approach.
Hampton v. Benefits Review Board,
The administrative law judge must consider “all relevant medical evidence”. 30 U.S.C. § 923(b). Although “no claim ... shall be denied solely on the basis of the results of a chest roentgenogram”,
ibid.,
the statute imposes no other limitation on the interpretation of evidence. The more evidence is available for decision, the more accurate the decision is likely to be. See
Peabody Coal Co. v. Director, OWCP,
A single positive (“qualifying”) x-ray film or test may create the presumption of disability, even though other films or tests do not show pneumoconiosis. The opinions in
Hampton
and
Whicker
expressed the view that it is illogical to say that “non-qualifying” films or tests do not prevent the creation of the presumption, while these same non-qualifying results may be used to rebut the presumption. There is nothing inconsistent about the process, however. A single x-ray or test may warrant casting the burden on the operator, yet other information of the same type, when put together with still more tests and examinations, may be part of a pattern that demonstrates the lack of total disability caused by pneumoconiosis. Objective evidence — x-rays, pulmonary function tests, blood gas tests — is the best available indicator of the extent of a respiratory impairment. See
Garrison v. Heckler,
The administrative law judge considered all of the available evidence and concluded that Ziegler had rebutted the presumption of disability. This decision is supported by substantial evidence. Cf.
