地质测井工作,常常要使用钴源、中子源等放射源。为保护测井人员的健康,我们采取了两项安全措施,取得了良好效果。 过去测井前,测井人员要用源钳将放射源从铅室里挟出,测完之后再放回,每测一个井,一般需40分钟左右。在这么长的放射时间内,由于无铅室屏蔽、放射线强度大,与人距 Geological logging work, often use cobalt sources, neutron sources such as radioactive sources. In order to protect the well logging staff, we have taken two safety measures and achieved good results. Before the well logging in the past, the logging staff used the source forceps to pinch out the radioactive source from the lead chamber, and then put it back again after measuring. Generally, it takes about 40 minutes for each well. In such a long time of radiation, due to lead-free room shielding, radiation intensity, and people from
