Low-level radiation exposures are expected to have long-term health implications but few near-term effects that would impair function. These assumptions are based on extrapolation from acute exposure responses, not on studies of a larger array of exp

Among the cytotoxic agents which particularly cause damage to cell renewal systems, ionizing radiation is one of the most effective ones since it leads to inactivation of all types of proliferating cells including resting stem cells. It is the aim of

In attempting to evaluate the possible health consequences of chronic ionizing radiation exposure during extended space travel (e.g., Mars Mission), ground-based experimental studies of the clinical and pathological responses of canines under low dai

The toxicity of {sup 137}Cs in the beagle dog was investigated at the Inhalation Toxicology Research Institute (ITRI) and Argonne National Laboratory (ANL) as part of programs to evaluate the biological effects of both radionuclides in atomic bomb fa

The effects of exposure to 60Co gamma rays for the duration of life on mortality patterns in beagles were investigated. Doses of 3, 7.5, 18.8, 37.5, 75, 127.5, 262.5, 375, or 540 mGy were delivered over a 22-h day 7 days a week. Hazard models with ti

The effects of protracted exposure to 60Co gamma rays on survival and tumor induction in the beagle were investigated. Total accumulated doses of 450, 1050, 1500, and 3000 cGy were given at rates of 3.8, 7.5, 12.8, and 26.3 cGy/day. Hazard models wer

Observations made after 48 h of cultivation show that 52% of dog lymphocytes are already in M 2 and 17% in M 3 at that fixation time. Evidently, the large discrepancy observed between man and dog with respect to the yield of dicentric chromosomes ind

A high incidence of leukemia in adult beagle dogs was induced by continuous whole-body exposure to low doses of 60Co gamma irradiation. At 5, 10, and 17 R per 22-hr exposure day, 20 animals of 53 died of either myelogenous leukemia (15 of 20) or eryt

Lymphocytic orchitis occurs spontaneously in a closed colony of beagle dogs with an incidence of 32% among 69 untreated males over 1 year of age. This disease is genetically influenced as determined by an analysis of the ancestral composition of each

Aplastic anemia and myelogenous leukemia are prominent pathologic effects in beagles exposed to continuous, daily, low-dose gamma irradiation. In the present work, granulocyte reserves and related mobilization functions have been sequentially assesse
