Categories radiation working conditions: For ease of administration, the working conditions of radiation into three types: A Species Working conditions: effective radiation dose equivalent a year may exceed 15mSv (1.5rem). For such working conditions of staff, to have personal dose monitoring of places to have regular monitoring of radiation protection project, the establishment of individual staff radiation doses and archives by workplace monitoring. B kinds of work conditions: effective dose equivalent radiation is less likely than a year 15mSv (1.5rem). But there may be more than 5mSv (0.5rem). For such places working conditions, to be monitored on a regular basis. To make a personal dose monitoring and establish individual doses to file. Gamma Working conditions: effective dose equivalent radiation is less likely than a year 5mSv (0.5rem) working conditions for this place, can be monitored according to needs, and recorded. .
