VGuidelines for exposure to visible and infrared radiation were first proposed by ICNIRP in 1997. Related guidelines on limits of exposure to ultraviolet radiation (UVR) and laser radiation have been published. This document presents a revision of the guidelines for broadband incoherent radiation. Health Phys. 105(1):74Y96; 2013
Dr Cherry was invited by the Ministry of Health/ Ministry for the Environment of New Zealand to carry out a peer-review of the proposal to adopt the ICNIRP guidelines for cell sites in New Zealand, in November 1999. The ICNIRP guidelines were covered by a published assessment in 1998. This review shows that the assessment had ignored all published studies showing chromosome damage. It was highl...
Wireless power transfer (WPT) technology using the resonant coupling phenomenon has been widely studied, but there are very few studies concerning the possible relationship between WPT exposure and human health. In this study, we investigated whether exposure to magnetic resonant coupling WPT has genotoxic effects on WI38VA13 subcloned 2RA human fibroblast cells. WPT exposure was performed usin...
Introduction: Communication between mobile phones and antenna BTS (Base Transceiver station) is carried by electromagnetic waves. Energy associated with these waves can be absorbed by biological tissues. so Widespread use of these devices has generated public concern about exposure to electromagnetic waves. In this study the electric field intensity and specific absorption rate...
Exposure to radiofrequency (RF) radiation was classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO in 2011. The exposure pattern is changing due to the rapid development of technology. Outdoor RF radiation level was measured during five tours in Stockholm Old Town in April, 2016 using the EME Spy 200 exposimeter with 20 predefined freque...
Concern about the possible health effects from exposure to Extremely Low Frequency (ELF) electromagnetic fields is increasing worldwide. This paper presents analyses of measurements of low frequency magnetic and electric fields caused by conductors carrying current in the Oman electric power system. Measurements were taken during the summer period at around 3 PM to capture peak loads. Field mea...
Se evaluaron niveles de exposición desde equipos Magnetoterapia, Diatermia Quirúrgica y Terapéutica. No se observaron daños, pero si preocupación en los trabajadores; son menores que limites ICNIRP. Es necesario establecer Registros, para continuar con investigaciones a largo plazo
To avoid potentially adverse health effects, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has defined reference levels for time varying magnetic fields. Restrictions on the electric fields induced in the human body are provided based on biological response data for peripheral nerve stimulation and the induction of phosphenes. Numerical modeling is commonly used to ...
The International Agency for Research on Cancer (IARC) classifies electromagnetic fields (EMFs) as 'possibly carcinogenic' to humans that might transform normal cells into cancer cells. Owing to high utilisation of electricity in day-to-day life, exposure to power-frequency (50 or 60 Hz) EMFs is unavoidable. Melatonin is a natural hormone produced by pineal gland activity in the brain that regu...
