The estimation of absorbed dose rates for non-human biota: an extended intercomparison

Radiation and Environmental Biophysics, 2010
An exercise to compare 10 approaches for the calculation of unweighted whole-body absorbed dose rates was conducted for 74 radionuclides and five of the ICRP's Reference Animals and Plants, or RAPs (duck, frog, flatfish egg, rat and elongated earthworm), selected for this exercise to cover a range of body sizes, dimensions and exposure scenarios ...

Monte Carlo estimates of absorbed dose rate in various tissues and organs

European Journal Of Nuclear Medicine, 1987
A computer program based on the Monte Carlo technique was developed for calculation of absorbed dose rate in various tissues and organs. The accuracy of the program was tested by reproducing Berger's values of the specific absorbed fractions for point isotropic sources in water, and a good agreement with those obtained by the moments method was found ...

The Radon Concentration and Absorbed Dose Rate in Hungarian Dwellings

Radiation Protection Dosimetry, 1996
A survey of indoor radiation in Hungarian homes has been carried out by measuring the radon concentration and the dose rate from extemal sources in a thousand dwellings using electret radon detectors (E-PERM) and thermoluminescence dosemeters (CaSO 4 :Tm). The measurements were performed in one year during 1993-1994.

Terrestrial absorbed dose rate measurement in the Jhangar valley of Pakistan

Journal of Radioanalytical and Nuclear Chemistry, 2002
Specific activity of natural radionuclides; 226Ra, 232Th and 40K were measured in the agricultural soil of eastern salt range of Pakistan using gamma ray spectrometry. The soil samples were collected within the ploughing region (up to 12 cm depth) and processed before analysis.

Measured Absorbed Dose Rates From Semi-infinite Hemispherical Volumes of 133Xe

Health Physics, 1986
Surface absorbed dose rates from different hemispheric volumes of 133Xe have been measured directly with an extrapolation chamber. The results indicate that a linear relationship exists between the radius of the cloud volume and the surface absorbed dose rate for radii between 0 and 23 cm.

Estimation of Radioactivity Dose Rate Absorbed with Ingested Foods

2013
The purpose of the study was to estimate the effective dose of ionising radiation absorbed in consequence of consuming the selected food products for relevant age groups and estimation of the resulting risk. The study was carried out with the use of food products, part of which was produced in the area contaminated with 137 Cs released after the ...
