JOURNAL FREE ACCESSThe present discussions were focussed on the application of mathematical models to describe body or organ retention of nuclides for the evaluation of internal exposure in man.
The fundamentals of the compartment models such as definitions, necessary assumptions and some aspects of applications in the field of biological turnover studies were firstly interpreted.
The methods of compartmental analysis were introduced with deterministic as well as stochastic approach. The models utilized in ICRP publications of exponential and power functions were discussed with the underlying principles.
Shortcomings of compartment models, limitations on their applicability were also looked into and some trials to alter the models to fit the non-steady state or to fit the system having non-exchangeable part were introduced. Their applicability was examined through the cofitting to author's experimental data and the use of AIC.View full abstractDownload PDF (1469K) -
Statistical Judgement of Uncleanness in ElementsHideharu MATSUDA, Shigeko FURUKAWA, Tokishi KAMINISHI1977 Volume 12 Issue 1 Pages 13-17

JOURNAL FREE ACCESSGenerally thermoluminescence dosimeter element without any significant exposure shows a large exposure reading when it is unclean, and this phenomena makes it difficult to evaluate the real exposure dose.
In this report one of the methods for detecting the unclean elements is mainly described. We found that the residual value, the reading in the reader at twice, of unclean elements is significantly higher than that of clean elements exposed. As the residual value of each element is different and is not constant at every measurement, data on unclean element is rejected on statistical proccesing of all data, occasionally on referring to the glow curve. The results of the personal monitoring for the past four years, 100 monitoring periods, show that this method has been effective for the evaluation of personal exposure with an accuracy of 1 mrem per 2 weeks.View full abstractDownload PDF (718K) -

JOURNAL FREE ACCESSThe method practiced in Karlsruhe Nuclear Research Center in West Germany for the treatment of persons contaminated with radioactive substances is presented, classifying the contamination into three categories: 1) contamination of the surface of the body, 2) inhalation exposure and 3) wound contamination. The estimation of body burden of plutonium and the assessment of effectiveness of DTPA in removing incorporated plutonium after DTPA therapy performed in an accident which occurred in the above-mentioned Research Center are also described.View full abstractDownload PDF (2643K) -
