The results of a review of six decades of existing literature for 50% lethal dose data across a range of phyla are presented. The collected 50% lethal dose data is limited to adult organisms subjected to acute doses of gamma radiation. The data collected is examined to determine whether useful...
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....
The Nevada Test Site (NTS) was the location for at least 100 above ground
Nuclear Weapons tests during the 1950's and early 1960's. Radioactive fallout
from these tests spread to many areas north and west of the NTS. According to
estimates from the NCI and DOE, Washington County, Utah was...
Chlorine – 36 (36Cl) is produced naturally, through neutron activation of stable chlorine during nuclear weapons detonation, or from neutron capture on residual chlorine in graphite piles. It has a half-life of 301,000 years and decays by the means of beta decay with an average energy of 236.33 keV. Due...
It is widely recognized that the risks associated to both patients and medical personnel during therapeutic interventional procedures are greater than for other diagnostic studies due to the increased number, and complexity of the examinations resulting in increased radiation exposure. This report documents the practices of seven interventional radiologists at...
The advances in the nuclear sciences over the past sixty years have yielded many beneficial technologies and applications, such as power generation, food irradiation, and medical diagnostic devices and techniques. However, these advances have also allowed the advent of nuclear and radiological weapons. This paper will focus on one type...
The use of medical diagnostic imaging involving ionizing radiation has drastically increased in recent years causing concern about possible long term consequences such as the induction of cancer. Recognizing this recent trend, the
Institutional Review Board (IRB) at the Nebraska Medical Center commissioned this study in order to determine effective...
A thesis presented on the determination of factors related to deposition, clearance, and dosimetry of the ICRP 30 lung model as related to smoking. Variations in calculations used to determine radiation doses leave a need to determine a standard method to determine absorbed dose from smoking. Standard parameters are used...
As the field of radiation therapy evolves new treatment techniques will be
established. An example of an evolving treatment technique is respiratory gated
radiation therapy (RGRT). Research and studies have shown that RGRT can be used
to account for tumor motion as a result of respiratory motion. With evolving
technology...
The photoneutron production from three Varian linear accelerators ranging in energies from 6 MV to 23 MV has been investigated. Photoneutrons are produced during (γ, n) interactions with materials located within the treatment head. These unwanted neutrons not only increase patient dose, but may also lead to the requirement of...
