Alpha radiation-induced cell killing was determined in four different laboratories in order to: 1) measure interlaboratory variability and 2) compare the effects of radon and radon daughter exposures with the effects of 238 Pu (an often-used model fo

Because radon and its progeny (referred to collectively here as radon) emit alpha particles with a wide range of energies, as well as beta particles and gamma-rays, it is important to quantitate the relationship between initial damage induced by rado

A linear dose response was observed for radon-induced mutations at the CHO-hprt locus with an induction frequency of 1.4 x 10(-4) mutants per viable cell per gray. Mutants isolated after two levels of radon exposure were evaluated using Southern blot

The cytotoxic and mutagenic effects of radon and its progeny were compared in murine lymphoblast L5178Y-R16 cells after exposure at three institutions. The cells were exposed to 222Rn at Case Western Reserve University (CWRU) and Pacific Northwest La

We have developed a model to calculate the dose to the cell nucleus in cells exposed in suspension to radon and/or radon progeny. The model addresses the influence of (1) different radiation qualities and energies in the irradiation milieu; (2) the c

DNA damage was induced in isolated human peripheral lymphocytes by exposure at 5 Gy to 60Co radiation. Cells were permitted to repair the DNA damage while exposed to 60-Hz fields or while sham-exposed. Exposed cells were subjected to magnetic (B) or

The linear no-threshold extrapolation from a dose-response relationship for ionizing radiation derived at higher doses to doses for which regulatory standards are proposed is being challenged by some scientists and defended by others. It appears that

We read with interest the recent paper by Stinchcomb and Roeske (1) on the microdosimetric analysis of C-18 cells irradiated by ac particles. The data used in their analysis were from Argonne National Laboratory experiments. These data have also been

The effects of single and split doses of spirohydantoin mustard on the growth delay and cell survival of 9L rat brain tumor multicellular spheroids have been investigated. Treatment with 10-25 microM concentrations of spirohydantoin mustard inhibited
