The purpose of this study is evaluate the likelihood that exposure to nonionizing electromagnetic radiation (NIEMR) poses a risk or is a risk factor for the development of cancer in humans. This investigation provides evidence that exposure to EM fields and the thundering results related various cancers, most notably leukemia, lymphoma, and brain cancer caused of EM fields

Diamond detectors are well known for their radiation hardness and high drift speeds of both electron and holes making them ideal as start detectors placed in the beam. However, due to the large effective energy needed to create electron hole pairs (13 eV) the charge created by minimum ionizing particles (MIPS) traversing the diamond is marginal (8000 pairs for a 300 μm thick diamond) [1]. In th...

A substantial body of scientific evidence indicates that exposures to common chemicals and radiation, alone and in combination, are contributing to the increase in breast cancer incidence observed over the past several decades. Key recurring themes in the growing scientific literature on breast cancer and environmental risk factors are: (a) the importance of understanding the effects of mixture...

Myth: Cell phones and other similar technology increase the risk of brain tumors. Answer: Lawsuits and news headlines have fueled the myth that cell phones cause cancer, particularly brain cancer. According to a survey by Gansler (2008), about 30% of Americans believe the myth. Cell phones are clearly visible in society. Statistics show that 79% of the U.S. population and 90% of European and As...

Background The cardiovascular magnetic resonance (CMR) is usually complements echocardiography, provides a nonionizing radiation evaluation of congenital heart disease(CHD). The congenital air way malformation occur significantly more patients with CHD than patients without CHD. Echocardiography can not show air way well and CT can show air way very well. MRI has emerged as a powerful approach ...

Conventional X-ray-based cystography uses radio-opaque materials, but this method uses harmful ionizing radiation and is not sensitive. In this study, we demonstrate nonionizing and noninvasive photoacoustic (PA) and fluorescence (FL) cystography using clinically relevant indocyanine green (ICG) in vivo. After transurethral injection of ICG into rats through a catheter, their bladders were phot...

The design, development and operation of a network for the monitoring of the nonionizing electromagnetic radiation in Greece is presented in this paper. Two independent sub-networks, called “Hermes” and “pedion24” have been operating since November 2002 in several areas, and more than 4,000,000 electric field strength measurements have been conducted to date. The measurement results indicate th...
