A standard radon-222 source for the system of high-accuracy monitoring of radon-hazardous facilities in Ukraine
This scientific paper describes the creation procedure and use of the radon-222 generator based on uranium ore. The research done resulted in selection of an optimal uranium ore composition. Based on temperature field computations we selected the uranium ore capsule material. A standard source struc...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | This scientific paper describes the creation procedure and use of the radon-222 generator based on uranium ore. The research done resulted in selection of an optimal uranium ore composition. Based on temperature field computations we selected the uranium ore capsule material. A standard source structure has been suggested. Optimal options of the use of uranium ore specimens for the generator, volumetric activity standard and also for the device calibration were specified. The monitoring of some real radon-hazardous facilities, using the devices calibrated by standard radon-222 sources, showed a considerable overstepping of the volumetric activity of radon-222 in comparison with available standards. |
