Pet owners often assist voluntarily while their pets are being X-rayed during a medical examination. Medical staff members occupationally exposed to radiation are monitored regularly, as they wear personal dosemeters, whereas no dose measurements are carried out on voluntarily assisting persons, as measurements are both cost- and time-intensive. However, the dose limits prescribed in the German radiation protection regulations have to be observed for these volunteers as well. To assist the legislator in deciding whether the German regulation should be changed so that in future the dose of voluntarily assisting persons should also be determined-either by wearing a dosemeter or in another way-investigations with regard to the radiation dose exposure suffered by volunteers were performed within the scope of a research project. The personal dose equivalent Hp(10) for persons assisting knowingly and willingly in X-ray examinations in veterinary medicine was measured for different examination scenarios. Typical exposure situations have been identified and measurements performed in the field of scattered X-rays. The measurements were carried out on animals in veterinary practices and, to verify these measurements, also under laboratory conditions. This paper deals with X-ray examinations of large animals, with the focus especially on horses. The measured personal dose equivalent values of voluntary helpers in equine radiology are in the order of a few microsieverts.
在宠物进行医学检查接受X光照射时，宠物主人经常会自愿提供协助。职业暴露于辐射的医务人员会定期接受监测，因为他们佩戴个人剂量计，而对于自愿协助的人员则不进行剂量测量，因为测量既耗费成本又耗时。然而，这些志愿者也必须遵守德国辐射防护法规规定的剂量限值。为了协助立法者决定是否应更改德国法规，以便将来也确定自愿协助人员的剂量——无论是通过佩戴剂量计还是其他方式——在一个研究项目的范围内，对志愿者所遭受的辐射剂量暴露进行了调查。针对不同的检查场景，测量了在兽医学中明知且自愿协助X光检查的人员的个人剂量当量Hp(10)。已识别出典型的暴露情况并在散射X光领域进行了测量。这些测量是在兽医诊所的动物身上进行的，并且为了验证这些测量结果，也在实验室条件下进行了测量。本文涉及大型动物的X光检查，尤其侧重于马匹。在马的放射学中，自愿协助者的个人剂量当量测量值为几微希沃特量级。
