A method of providing in vivo measurement of entrance skin exposure for mammography using mailed thermoluminescent dosimeters has been developed. The dosimeters are calibrated to 137Cs (662 keV), and a correction is applied to account for energy response. A mailed dosimeter packet which can be used to measure the half-value layer at mammography energies is also described. The results for both systems agree well (to within 10%) with careful ion chamber determinations. These dosimeter measurements provide a simple. Inexpensive means to reliably determine exposure and to monitor machine parameters on a periodic basis.
已开发出一种使用邮寄热释光剂量计对乳腺摄影的入射皮肤暴露进行体内测量的方法。剂量计针对¹³⁷Cs（662 keV）进行校准，并应用校正以考虑能量响应。还描述了一种可用于测量乳腺摄影能量下半价层的邮寄剂量计包。两个系统的结果与使用精密电离室测定的结果吻合良好（在10%以内）。这些剂量计测量提供了一种简单、廉价的手段，可可靠地确定暴露情况并定期监测机器参数。
