Environmental modeling as a result of the Fukushima accident has been at the forefront for present day health physics. The accident released radionuclides in the environment and the fate and transport of these radionuclides are of interest when considering doses to non-human biota. The Pale Grass Blue Butterfly was studied...
The objective of this research was to estimate the radiological impact on various non-human biotas by the Fukushima Daiichi Nuclear power plant radiation release resulting from Japan's tsunami in March 2011 consistent with the recent recommendations of the International Commission on Radiological Protection. Soil concentration data given by Japan's Ministry...
In the last decade regulatory bodies have begun to implement standards to protect populations of non-human biota (NHB) from the consequences of radiation exposure. This is a departure from previous regulatory frameworks which were concerned only with protecting man. The implementation of these new standards has started an ongoing discussion...
The urban hydrology and hydraulics program, US EPA SWMM 5, has been coupled with a compartment model of a wastewater treatment plant (WWTP) in the system dynamics software, STELLA, to simulate the radiocesium pathway from urban catchment to the wastewater treatment sludge. Two literature case studies were re-examined. Firstly, a...
A system for radiological dosimetry for nonhuman biota developed by International Commission on Radiological Protection (ICRP) relies on calculations that utilize the Monte Carlo simulations of simple, ellipsoidal geometries with internal radioactivity distributed homogeneously throughout. In this manner it is quick and easy to estimate whole-body dose rates to biota....
A unique tumor targeted method, which may be able to deliver a molecule to the surface of a tumor cell using the pH gradient between hypoxic tumor cells and normal tissue has recently been developed. Since solid tumors have been found to have a lower extra cellular pH compared to...
Decon Gel 1101, is an uncomplicated, low odor, peelable polymer hydrogel for
use with radiological decontamination, manufactured by Cellular Bioengineer Inc. The
gel allows for single or multiple material applications to contaminated surfaces. As the
gel dries it binds the contaminant by encapsulating and lifting the contaminant into the
gel....
Mathematical modeling plays a pivotal role in understanding the mechanism of radiation-induced cellular effects, and also in quantifying the radiation risk to the cell. However, there are still compelling challenges facing the conventional modeling in radiobiology, such as lacking a generalized theory structure of quantifying target effect and non-target effect...
