The influence of radioactive source decay on measuring error of the isotope instruments is analysed. The valuable conclusion for designing the circuit of instrument is obtained.
Radiation protection - Sealed radioactive sources Leakage test methods???
Some suggestions are given on reforming the security control and surveillance of sealed radioactive sources: (1) carrying out "birth to death" notification and check for sources;
The utility model is convenient, quick and precise to use and can indicate the correction of the action spot of the radioactive source and the laser positioning.
There were relatively more responsible accidents in Xinjiang, and the future key points of management of radioactive sources should be focused on building up the safety awareness.
Both ends of the radioactive stent with appearance of column mesh is in smooth bell-mounted shape, and a radioactive source is plated or welded in a side area of the stent back end.
Brachytherapy is a method of treatment in which sealed radioactive sources are used to deliver radiation at a short distance by interstitial, intracavitary.
Sealed radioactive sources--Leakage test methods
High activity cobalt-60 sealed radioactive sources
The two radioactive sources will also be transported to safe areas soon, he said.
Unbeknown to them, the "scrap" contained a highly radioactive source used to treat cancer patients.
Brachytherapy means placing packed radioactive source near or on the surface of tumor via body cavity, or embedding fine needle in tumor to import radioactive source.
