New human data versus estimates of effects of inhaling fission product mixtures.

Recently, data on exposures of humans as well as animals to fission products in plumes emitted by underground Soviet tests have been declassified by the Khazakhstan government and published in English. Similar human intakes of gross fission product mixtures that caused acute prodromal symptoms have not been previously reported. Animal experiments with such complex mixtures have not received sufficient support to provide data that could be reliably extrapolated with dose-response models to humans for use in triage of internally exposed persons.

Radioanalytical data interpretation when the ratio reading/median is lognormally distributed.

The purpose of this paper is to assist those who might be confronted by non-normal and non-homoscedastic error distributions representable by continuous probability density functions. Methods are presented to demonstrate how mathematical algorithms can be developed to obtain a "best fit" calibration line and how uncertainty ranges in interpretations of unknowns can be obtained from the calibration. The data used to demonstrate these methods were obtained from Brookhaven National Laboratory fission track analysis data for plutonium in urine.
