The utility model belongs to the radiation source application, concretely relates to radiation source pneumatic conveying control detection device. Current radiation source pneumatic transmission system can't accurately control the position of locating with definite radiation source in the use, there is the accident in personnel and shines the risk. The utility model provides a radiation source pneumatic conveying control detection device, include the air compressor who is connected through the air flow transport pipeline with the radiation source holding vessel, the airflow channel and the radiation source channel that are equipped with mutual intercommunication in the radiation source holding vessel, an airflow channel of air flow transport pipeline connection radiation source holding vessel, the radiation source channel of radiation source holding vessel connects radiation source conveying pipe, is equipped with a plurality of air compressor 0 that the radiation source passes through that are used for responding to outside radiation source conveying pipe, and air compressor 0 is connected with air compressor 2. Adopt the utility model provides a transfer operation of radiation source can be controlled to the device, accurate masters the position that the radiation source was located in operation process, prevents to cause the accident to shine because of the radiation source position is not quite clear to personnel.
