A compartmental model of the distribution of radium in humans and young adult beagle dogs (approximately 500-550 d) is presented. The model consists of one soft tissue compartment and seven skeletal compartments for humans, and five skeletal compartm

This paper considers the utility of a stochastic model of carcinogenesis, proposed earlier by Yakovlev and Polig, in quantitative analysis of the incidence of radiation-induced osteosarcomas in beagels injected with various amounts of ^2^3^9Pu. The o

A three-stage model for the induction of bone tumors in beagles from single injections of ^2^3^9Pu is presented. The model involves branching with one or two initiation steps controlled by radiation. It was applied to six groups of animals with grade

A biokinetic model of the systemic distribution and dosimetry of 239Pu in the beagle dog is presented. To achieve maximum consistency with experimental data, known histomorphometric parameters and results of autoradiographic studies were adopted dire

The microdistribution Of 239Pu was analyzed in the humerus, lumbar vertebra, and proximal ulna of young adult beagles using neutron induced autoradiography. The animals were sacrificed serially in groups of three at 4, 8, 16, 32, and 64 wk after a si

Uranium isotopes were given via single intravenous injection into 22 young adult beagle dogs of both sexes to determine the metabolism of this element. Animals were given either {sup 232}U, {sup 233}U, {sup 238}U, or a combination of {sup 232+233}U.

The mean dose and number of hits to nuclei of osteoblasts and their progenitors from expanding volume sources of α-emitters labelling newly formed bone is calculated. It is assumed that these cells only accumulate a radiation dose or nuclear hits du

The stochastic aspects of alpha-particle traversals through nuclei of bone-lining cells from nonuniform radioactive labels are worked out. Both the residence time of the target and the hit rate are considered random variables. It is shown that with a
