Science-informed Policy Making for Protecting People and the Environment from Radiation.

The process to arrive at the radiation protection practices of today to protect workers, patients, and the public, including sensitive populations, has been a long and deliberative one. This paper presents an overview of the US Environmental Protection Agency's (US EPA) responsibility in protecting human health and the environment from unnecessary exposure to radiation. The origins of this responsibility can be traced back to early efforts, a century ago, to protect workers from x rays and radium.

The effect of temperature conditions during growth on the transformation frequency of obtained by electroporation.

In this study, we have shown that transformation efficiency of C-169 obtained by electroporation can be significantly increased by either supra- or sub-optimal growth temperatures.

Methodological improvements to meta-analysis of low dose rate studies and derivation of dose and dose-rate effectiveness factors.

Epidemiological studies of cancer rates associated with external and internal exposure to ionizing radiation have been subject to extensive reviews by various scientific bodies. It has long been assumed that radiation-induced cancer risks at low doses or low-dose rates are lower (per unit dose) than those at higher doses and dose rates. Based on a mixture of experimental and epidemiologic evidence the International Commission on Radiological Protection recommended the use of a dose and dose-rate effectiveness factor for purposes of radiological protection to reduce solid cancer risks obtained from moderate-to-high acute dose studies (e.
