Foreword

According to "People's Republic of China Occupational Disease Prevention Law" to develop this standard. In the revision of this standard, the main reference of the International Atomic Energy Agency IAEA No. 37 Safety Standards "lead because the intake of radionuclides Estimation of occupational radiation dose from the "(2004). This standard replaces GB/T 16148-1995 "radionuclide intakes and internal radiation dose estimates specification." This standard compared with GB/T 16148-1995, the main changes are as follows. --- Respiratory tract, including the illumination model, the original standard is based on the model number ICRP30 publications, and this standard is based on ICRP66 Model number of publications; --- In the case of occupational exposure, using GB Z129-2002 "within individual occupational exposure monitoring standards" recommended intake estimates Party French alternative methods intake or intake excretion function value retention function value estimate; --- When performing internal radiation dose estimates with intake, using the ICRP publication of 67,69,71 and 72 organizations have recommended the product to be [(DCF) 50, T, (DCF) 50, E]. The Standard Appendix A, Appendix B, Appendix C, Appendix D is an informative annex. This standard is proposed and administered by the People's Republic of China Ministry of Health. This standard by the People's Republic of China Ministry of Health is responsible for interpretation. This standard was drafted. Chinese Academy of Medical Sciences Institute of Radiation Medicine. The main drafters of this standard. Liuqing Fen, Liu Qiang, Wu Quan, Fan body strong, Zhang Liangan. This standard replaces the standards previously issued as follows. --- GB/T 16148-1995. Radionuclide intakes and internal doses Estimation standards

1 Scope

This standard specifies the measurement and estimation of radionuclide intake, internal radiation dose estimates and methods, and uncertainty estimation sit Consider factors. This standard applies to occupational and public exposure of radionuclide intakes and internal radiation dose estimation work.

2 Normative references

The following documents contain provisions which, through reference in this standard and become the standard terms. Where dated references, which subsequently Some amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Study whether the latest versions of these documents.

3 Terms and Definitions

The following terms and definitions apply to this standard. 3.1 The amount of radionuclide into the body. Its way into the inhalation, ingestion and through a wound or intact skin. 3.2 After the amount of ingested into the extracellular liquid radionuclides. 3.3 Intake of radionuclides at different times after staying in organs, tissues within the body of radionuclides or amount. Radionuclide uptake body fluid volume Called retention system. Retention systems and in the respiratory tract and the gastrointestinal tract and retention of said body retention. 3.4 After ingested, deposited in the organs of radionuclide intake amount of radioactivity. For example, after an acute inhalation deposition in the gastrointestinal tract Radionuclide amount. 3.5 Used to estimate the intake of radionuclides through breathing mathematical models. HRTM divided into a front nose portion of the airway ET1, throat ET2 (the Road and posterior nasal tone composition), the trachea and main bronchi BB, bb and bronchioles vesicles void AI (gas exchange) five zones. ET1 and ET2 collectively known as the head of airway ET, lymphocytes related to this area. BB, bb and AI are three areas of the chest. 3.6 Used to estimate the intake of radionuclides through ingestion way of mathematical models. It means the ICRP model of the gastrointestinal tract, usually divided into stomach, small Intestine, large intestine the upper section and the lower section of the large intestine of four parts. In the calculation of the effective dose, four parts by an independent organ treatment. ......
