Absorbed Dose News Today

This is a primer on the way the wind has been blowing since the Ukrainian ammunition stockpile was blown up at Khmelnitsky in the early hours of May 13. Radiation measurements in the western Ukrainian city appear to have risen sharply on May 13...

Objective. Reference dosimetry on an MRI-linac requires a chamber specific magnetic field correction factor, kB -. This work aims to measure the correction factor for a parallel plate chamber on a parallel MRI-linac. Approach. kB→is defined as the ratio of the absorbed dose to water calibration coefficient in the presence of the magnetic field, ND,wB→relative to that under 0 T conditions, ND,w0T. kB→was measured via a ND,w transfer to a field chamber at each magnetic field strength from a ...

The Million Person Study , led by the National Council on Radiation Protection and Measurements, is a collaborative effort of researchers at multiple institutions including ORISE, Oak Ridge National Laboratory, Memorial Sloan Kettering Cancer Center, Vanderbilt University, and others, to study the health effects of chronic low-dose radiation exposu

Radioactivity is all around us, both from natural and artificial sources. But it is usually invisible, so how do we tell if it is there? There are quite a few passive and electronic methods for detecting and classifying radiation. This article investigates radioactivity, radioactive sources and ways to measure radioactivity electronically, including Geiger counters. by Dr David Maddison
