Internal Dosimetry Evaluations

Health Physics, 1986
A 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, 2003
Various 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, 2003
Data 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, 2010
This 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.

Progress with the NCT international dosimetry exchange

Applied Radiation and Isotopes, 2004
The international collaboration that was organized to undertake a dosimetry exchange for purposes of combining clinical data from different facilities conducting neutron capture therapy has continued since its founding at the 9th ISNCT symposium in October 2000.

Thermoluminescent Internal Beta-Ray Dosimetry

Radiation Research, 1967
The possibility of using thermoluminescence for in vivo and in vitro direct dose measurements in tiny body cavities (for example, bone marrow) suggested investigation of the response to beta radiation of LiF and CaF2 powder and single crystals of different thicknesses (down to microns).

UK laboratory intercomparison on internal dosimetry

Radiation Protection Dosimetry, 2003
A laboratory intercomparison for internal dose assessment from a variety of intake scenarios is described. This is the first UK intercomparison using the revised ICRP Human Respiratory Tract and biokinetic models. Four United Kingdom laboratories participated and six cases were assessed.

The contribution of chemical speciation to internal dosimetry

Radiation Protection Dosimetry, 2003
Speciation studies refer to the distribution of species in a particular sample or matrix. These studies are necessary to improve the description, understanding and prediction of trace element kinetics and toxicity. In the case of internal contamination with radionuclides, speciation studies could help to improve both the biokinetic and dosimetric ...

Internal Radiation Dosimetry

1993
Radiation can cause detrimental effects on human tissues, and these effects depend on various factors, such as dose, dose rate, time of exposure and so on. This chapter describes the method of calculating absorbed doses in various organs from radionuclides ingested internally either purposely (e.g., medical procedures) or accidentally.
