TRANSVAGINAL CESIUM 137 THERAPY

American Journal of Roentgenology, 1967
1. Transvaginal irradiation is indicated in: patients with cancer of the cervical stump, with hemorrhaging cancer of the cervix, and in patients where intracavitary radium treatment is not possible for cancer of the cervix uteri.2. Transvaginal cesium 137 therapy is made practical by adapting del Regato applicators to the teletherapy unit, and may be ...

Seasonal Cycling of Cesium-137 in a Reservoir

Science, 1979
Studies of a reservoir in the southeastern United States show that cesium-137, introduced into the system from a leak in a nuclear fuel element, cycles between the water and sediment on a seasonal basis. The cycling, which coincides with the annual periods of thermal stratification in this monomictic lake, has been occurring for over 10 years.

Cesium-137 source strength verification

Medical Dosimetry, 2000
Over the years, the protocol for Cesium-137 source calibration has undergone a number of revisions based on updated data. The 3M Corporation issued product alerts and a revision of the calibration protocol in the early 1980s. We verified the activity of clinically used cesium tubes and found the difference with the activity stated by 3M in the range of

Separation and determination of Cesium-137 in urine

Analytica Chimica Acta, 1971
Abstract A method is described for the analysis of 137 Cs in either raw or ashed urine. The method relies upon an ammonium molybdophosphate ion exchange and solvent extraction with 4-sec-butyl-2-(α-methylbenzyl)phenol in order to collect and separate 137Cs from interfering activity. The analysis time on 11 of urine is ca .

I. Cesium-137 Metabolism in Man

Radiation Research, 1963
The study of the metabolism and distribution of cesium-137 is of particular interest at present because it is a biologically important fission product present in radioactive fallout. Animal experiments have shows species differences in the excretion patterns of parenterally and orally administered Cs137.

First Impressions of Therapy with Cesium 137

Radiology, 1957
Early in 1955 a kilocurie cesium-137 teletherapy machine was installed in the Medical Division of the Oak Ridge Institute of Nuclear Studies. After much preliminary physical work involving radiation protection surveys and isodose plotting, the machine was made available for limited clinical trial.

Distribution of Fallout Cesium-137 in Hawaii

Health Physics, 1984
The concentration of 137Cs was determined by gamma spectrometry in soils and surface-deposited volcanic sublimates from various climatic locations on the islands of Hawaii, Oahu and Maui. A distinct pattern of higher concentrations on the wetter windward sides of the islands and a correlation between 137Cs concentration and amount of rainfall were ...

The Cesium-137 Thermoelectric Generator

IRE Transactions on Military Electronics, 1962
Designed for the initial application of supplying power for an under-sea seismic station to be supervised by Lamont Geological Observatory researchers, this cesium generator incorporates an external shell that will withstand compressive forces at the greatest of ocean depths and a power-conversion system employing lead telluride thermocouples mounted ...

[Suicide with cesium-137].

Psychiatrie, Neurologie, und medizinische Psychologie, 1978
Reported first case of suicide with radioactive substance in Bulgaria. Male, aged 30, defectoscopist, with cyclothymic structure of character and psychotraumatic family environment made a second and successful attempt at suicide, this time by means of outer irradiation with cesium-137 with an activity of 5.3 curie in the course of two hours--irradiated

Cesium-137 Decorporation Model

2014
Abstract : A treatment model for Cs-137 internal contamination by Prussian Blue was developed to evaluate efficacy of various treatment regimens. The model estimates Cs deposition, absorption, distribution, retention, excretion, and response to DTPA after an inhalation exposure.
