sec.51Definitions for division

### sec.51 Definitions for division In this division— external effective dose , received by a person, means the total of the weighted equivalent doses for all organs and tissues of the person as a result of exposure of the organs and tissues to radiation emitted from ionising radiation sources external to the person’s body. health-related exposure , of a person to ionising radiation, means the exposure of the person to ionising radiation— while undergoing a diagnostic or therapeutic procedure involving the irradiation of the person; or while involved in carrying out a diagnostic or therapeutic procedure involving the irradiation of a person, other than as occupational exposure or as the treated person; or while involved in carrying out a radiation practice, as a voluntary participant in health-related research. internal effective dose , received by a person, means the effective dose from a radionuclide inhaled, ingested or introduced into the person’s body, calculated in accordance with— the document called ‘Occupational Intakes of Radionuclides: Part 1 ’, and known as ‘ICRP Publication 130’ prepared by the International Commission on Radiological Protection; and the relevant part of the series called ‘Occupational Intakes of Radionuclides’ for the radionuclide. s 51 def internal effective dose amd 2023 SL No. 146 s 13 (1) natural background exposure , of a person to ionising radiation, means the exposure of the person to ionising radiation occurring naturally in the environment. occupational exposure , of a person to ionising radiation, means the exposure of the person to ionising radiation in the course of the person’s work, other than exposure that is natural background exposure. public exposure , of a person to ionising radiation, means the exposure of the person to ionising radiation, other than exposure that is health-related exposure, natural background exposure or occupational exposure. relevant part , of the series called ‘Occupational Intakes of Radionuclides’, means any of the following documents— the document called ‘Occupational Intakes of Radionuclides: Part 2 ’, and known as ‘ICRP Publication 134’ prepared by the International Commission on Radiological Protection; the document called ‘Occupational Intakes of Radionuclides: Part 3 ’, and known as ‘ICRP Publication 137’ prepared by the International Commission on Radiological Protection; the document called ‘Occupational Intakes of Radionuclides: Part 4 ’, and known as ‘ICRP Publication 141’ prepared by the International Commission on Radiological Protection; the document called ‘Occupational Intakes of Radionuclides: Part 5 ’, and known as ‘ICRP Publication 151’ prepared by the International Commission on Radiological Protection. s 51 def relevant part amd 2023 SL No. 146 s 13 (2) total effective dose , for a person for a period, means the total of the external effective doses and the internal effective doses received by the person during the period. weighted equivalent dose , for a person’s organ or tissue that is exposed to radiation, means the product of— the tissue weighting factor for the organ or tissue stated in the glossary of the document called ‘Code for Radiation Protection in Planned Exposure Situations’ (2020) published by ARPANSA; and the equivalent dose for the organ or tissue. - (a) while undergoing a diagnostic or therapeutic procedure involving the irradiation of the person; or - (b) while involved in carrying out a diagnostic or therapeutic procedure involving the irradiation of a person, other than as occupational exposure or as the treated person; or - (c) while involved in carrying out a radiation practice, as a voluntary participant in health-related research. - (a) the document called ‘Occupational Intakes of Radionuclides: Part 1 ’, and known as ‘ICRP Publication 130’ prepared by the International Commission on Radiological Protection; and - (b) the relevant part of the series called ‘Occupational Intakes of Radionuclides’ for the radionuclide. - (a) the document called ‘Occupational Intakes of Radionuclides: Part 2 ’, and known as ‘ICRP Publication 134’ prepared by the International Commission on Radiological Protection; - (b) the document called ‘Occupational Intakes of Radionuclides: Part 3 ’, and known as ‘ICRP Publication 137’ prepared by the International Commission on Radiological Protection; - (c) the document called ‘Occupational Intakes of Radionuclides: Part 4 ’, and known as ‘ICRP Publication 141’ prepared by the International Commission on Radiological Protection; - (d) the document called ‘Occupational Intakes of Radionuclides: Part 5 ’, and known as ‘ICRP Publication 151’ prepared by the International Commission on Radiological Protection. - (a) the tissue weighting factor for the organ or tissue stated in the glossary of the document called ‘Code for Radiation Protection in Planned Exposure Situations’ (2020) published by ARPANSA; and - (b) the equivalent dose for the organ or tissue.
