Introduction: After the lead poisoning outbreak came to light in Zamfara State, Nigeria, people living near gold mines were worried about environmental safety, especially drinking water quality. This study examined the gross alpha and gross beta activity concentrations in groundwater in different locations of Anka, Zamfara State, Nigeria, to measure the possible radiation dose and potential hea...

A study on Magnetohydrodynamic (MHD) flow past an accelerated vertical plate with the effects of thermal radiation and chemical reaction has been carried out. The dimensionless governing equations are solved using Laplace transform technique. solution for velocity, temperature concentration field obtained analyzed different physical parameters like Grashof Number, Modified permeability paramete...

Introduction: Although there are several ways to relief pain in metastatic patients, the use of radionuclides is one of the known and effective ways to relieve the pain caused by bone metastases. The purpose of this study was to assessment of radiation dose distribution of different radioisotopes used to treatment and pain relief patients in a bone-based model based on Monte C...

The International Centre for Low-Dose Radiation Research (ICLDRR) has assembled, in a single database, all published results from experimental radiation carcinogenesis in mammals. The database contains experimental conditions and outcomes for about 87,000 exposed animals (̃ 60,000 cancers) and 40,000 controls (̃ 19,000 cancers). Experiments were conducted with all types of ionizing radiation, at ...

Exposure to radiation in all its forms is part of being alive. Ionising radiation is taken to mean radiation of high-enough energy to displace electrons from atoms and includes cosmic rays, gamma rays, X-rays, alpha and beta radiation. The average level of exposure to natural background radiation varies throughout the world dependent mainly on the geology of the underlying earth. In the UK it i...

This study examined differential effects of alpha-(α-) particle radiation and X-rays on apoptosis and associated changes in gene expression. Human monocytic cells were exposed to α-particle radiation and X-rays from 0 to 1.5 Gy. Four days postexposure, cell death was measured by flow cytometry and 84 genes related to apoptosis were analyzed using real-time PCR. On average, 33% of the cells were...

Differences between the mechanisms of energy deposition by high-LET radiation, consisting of neutrons, protons, alpha particles, and heavy ions on one hand, and low-LET radiation, exemplified by electron beam and gamma radiation on the other, are utilized in the selection of types of radiation used for specific applications. Thus, high-LET radiation is used for modification of carbon nanotubes,...

The primary purpose of this chapter is to provide public health officials, toxicologists, and other interested individuals and groups with an overall perspective of the health physics and toxicology of ionizing radiation. It contains descriptions and evaluations of radiological and toxicological studies and epidemiologic investigations and provides conclusions, where possible, on the relevance ...

We develop an analytical ringdown waveform model, including both the fundamental and overtone quasinormal modes, for charged black holes show that it is precise enough to analyze current gravitational wave data. Applying this model GW150914, charge mass ratio of remnant hole (${\ensuremath{\lambda}}_{f}$) has been constrained with sole data first time 90% upper limit ${\ensuremath{\lambda}}_{f}...
