The comparison of toxicity classification of radionuclides

The toxicities of 1435 radionuclides, in respect to the lung ahsorption speed and physical state, were reclassified on the base of updated data. Then the toxicity reclassification of 851 radionuclides was listed by the combination according to the request for editing the State Standards entitled (Basic Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources). The list of new classification was compared with that of GB 4752 and GB 8703 and resulted to prove that all of them was similar as a whole, but some differences between them come from the changing of dose limits and dose conversion coefficients.
