normal 0 false false false en-us x-none fa background: the angular dependency of response for tld cards may cause deviation  from its true value on the results of environmental dosimetry, since tlds may  be exposed to radiation at different angles of incidence from the surrounding area. objective: a 3d setting of tld cards has been calibrated isotropically in a standard  radiation field to eval...

In a recent discussion relating to environmental health, Mark D. Hollis (1) indicated that public health officials will be responslible for protecting the population against the harmful effects of ionizing radiation. Ionizing radiations result from the disintegration of unstable nuclei and are damaging to living tissue. The radiation may originate from an external source or from radioactive mat...

The paper describes dosimetric models that allow the estimation of average radiation exposures to terrestrial biota due to environmental sources in the soil as well as internal uniform distributions of radionuclides. Simple three-dimensional phantoms for 13 faunal reference organisms are specified. The calculation of absorbed dose per unit source strength for these targets is based on photon an...
