• During the dosimeters transportation and stroge, background radiation shall measure due to natural radiation which happen by itself (cosmic and background )is available in our living space. Thus, Transport dosimeters is sent together with other dosimeters to give information about only occupational dose of radiation personals/workers. • In every period, dose value which is measured by transport dosimeter subtracted to dose value which is measured by personal/worker dosimeter. Do not use the transport dosimeter for any other purpose and stroge out of the radiation field. • Transport dosimeters shall be sent back together with other dosimeters to RADAT Dosimetry Lab after every period.
