Concept for Internal Dosimetry and Approval of Internal Dosimetry Services in Switzerland
Radiation Protection Dosimetry, 1994The new Swiss radiation protection regulations will require approval of the internal dosimetry laboratories. The procedures allow for two types of bioassay measurements: The «screening measurements» for the local staff using relatively simple instrumentation to make sure that no unexpected intake has occurred and the «incorporation measurements» by a ...

The internal dosimetry code PLEIADES
Radiation Protection Dosimetry, 2007The International Commission on Radiological Protection (ICRP) has published dose coefficients for the ingestion or inhalation of radionuclides in a series of reports covering intakes by workers and members of the public, including children and pregnant or lactating women.

International intercomparison for criticality dosimetry: the case of biological dosimetry
Radiation Protection Dosimetry, 2004The Institute of Radiation Protection and Nuclear Safety (IRSN) organized a biological dosimetry international intercomparison with the purpose of comparing (i) dicentrics yield produced in human lymphocytes; (ii) the gamma and neutron dose estimate according to the corresponding laboratory calibration curve.

Internal Dosimetry Evaluations
Health Physics, 1986A computerized approach to the average absorbed dose calculations in the standard human body is reported. For each selected radionuclide, a matrix S of the order n X n is constructed and stored in the computer. The matrix elements consist of the absorbed dose coefficients per unit cumulated activity (rad microCi-1 hr-1) for n different organs.

Developments in the internal dosimetry of radiopharmaceuticals
Radiation Protection Dosimetry, 2003Various radionuclides are used in nuclear medicine in different diagnostic and therapeutic procedures. Recently, interest has grown in therapeutic agents for some interesting applications in nuclear medicine. Internal dose models and methods in use for many years are well established, and can give radiation doses to stylised models representing ...

Target cells in internal dosimetry
Radiation Protection Dosimetry, 2003Data related to radium induced bone sarcomas in humans are used as a method of defining target cells on bone surfaces and in the bone marrow. The differential distribution of radiation induced bone sarcoma types, with a high ratio of non-bone producing, mainly fibroblastic tumours, challenges the ICRP concept that the bone lining cells are target cells.

New developments in internal dosimetry models
Radiation Protection Dosimetry, 2010This paper describes new biokinetic and dosimetric models, especially those being developed by ICRP which will be used in the forthcoming documents on Occupational Intakes of Radionuclides. It also presents the results of a working group within the European project CONRAD which is being continued within EURADOS.

Ionizing radiation has a lot of benefits and application in biomedical and life sciences. However, it also has several hazards and risks if not properly used and applied. Incorporation or administration of a radioactive compound within tissues and cells of human body might cause several risk consequences and effects if not minimized to safe levels for ...
