Radiology is being used to an increasing extent in the clinical diagnosis of hip lameness in bulls. Consequent gonadal doses may have important implications in later breeding programmes. Skin and gonadal doses were recorded during hip radiography of 18 bulls. An additional 0.13 mm copper filtration reduced skin dose by more than one third, but had no effect on gonadal dose. The average radiation dose to the gonads was approximately halved by completely surrounding the scrotum with lead sheeting 0.95 mm in thickness.
放射学在公牛髋部跛行的临床诊断中应用越来越广泛。随之而来的性腺剂量可能对后期的繁殖计划产生重要影响。在对18头公牛进行髋部放射成像时记录了皮肤和性腺剂量。额外增加0.13毫米的铜过滤可使皮肤剂量减少超过三分之一，但对性腺剂量没有影响。通过用厚度为0.95毫米的铅板完全包裹阴囊，性腺的平均辐射剂量大约减半。
