Because the weights of the two source tanks are about 100Kg and 60Kg respectively, and the door is opened at the upside of the bin position, the labor loading and unloading difficulty is large, the labor intensity is high, and the potential safety hazard of smashing and injuring personnel or vehicles is easy to occur;
2. the loading and unloading are carried out for 4 times after one-time logging operation is finished, and operators contact the source tank in a close range for a long time to cause great radiation damage to the operators;
3. the total surface radiation value of the source tank as a transport container, a neutron source tank and a density source tank is more than or equal to 1000 mu SV/h, and a source storage bin is not used as an effective and proper shielding device. The front side and the rear side door of the storage bin have larger radiation values. Due to the long logging time. And a large radiation potential safety hazard is formed to field logging operators and the surrounding environment.
