Research on Air Sampling Method of HTO in Radiation Control Area of the T Installation
HTO sampling and measurement in the radiation control area air is an important indicator of workplace environmental monitoring.In this experiment,the HTO in the radiation control area was quickly sampled and compared by syringe bubbling method,dehumidifier condensation method and liquid nitrogen freezing method.The results show that the sampling efficiency of the syringe bubbling sampling method is unknown,and it is not applicable under the existing conditions.The data of the dehumidifier condensation method and the liquid nitrogen freezing method are reliable and there is no significant difference between them,which can replace each other.However,the dehumidifier condensation method has the risk of cross-contamination,and requires external power supply,and the liquid nitrogen freezing method is dangerous and low-temperature operation.It is recommended to use the liquid nitrogen sampling method in the craft room and the laboratory uses the dehumidifier sampling method.
