The relative merits of tungsten and molybdenum targets for mammography have been the subject of much discussion. Therefore the spectra and outputs (at constant potential) from molybdenum and tungsten targets, interchangeable in the same tube, have been measured with a Ge(Li) detector and ion chamber respectively. All conditions apart from the target material were unaltered. The spectra have been corrected for the distortions produced by the detector. The effects of filtration on spectra and exposure rates have been calculated and are in agreement with measured values. The spectra and outputs from molybdenum and tungsten targets filtered by aluminium and molybdenum have been investigated and the results are discussed with reference to mammography and the radiography of specimens.
钨靶和钼靶在乳腺摄影中的相对优点一直是诸多讨论的主题。因此，分别使用锗（锂）探测器和电离室，对同一管中可互换的钼靶和钨靶在恒定电位下的能谱和输出进行了测量。除靶材外，所有条件均保持不变。已对探测器产生的畸变对能谱进行了校正。计算了过滤对能谱和曝光率的影响，计算结果与测量值相符。研究了经铝和钼过滤后的钼靶和钨靶的能谱及输出，并结合乳腺摄影和标本射线摄影对结果进行了讨论。
