Non-ionizing electromagnetic radiation monitoring in Greece

annals of telecommunications - annales des télécommunications, 2008
The design, development, and operation of a network for the monitoring of the non-ionizing electromagnetic radiation in Greece is presented in this paper. Two independent sub-networks, called “Hermes” and “pedion24” have been operating since November 2002 in many areas, and more than 4,000,000 electric field strength measurements have been conducted to

The Use of Non-Ionizing Radiation for Therapeutic Heating [PDF]

, 1975
Various forms of non-ionizing radiation are used for the therapeutic application of heat. As part of this symposium, a brief overview will be given on the use of therapeutic heat in the form of shortwave, microwave and ultrasonic radiation. Goals in therapeutic heat application are as follows: (1) to increase extensibility of collagen tissue; (2) to ...

Adaptive response induced by non-ionizing radiation

Toxicology Letters, 2017
The acquired resistance by cells and organisms pre-exposed to low doses of ionizing radiation or selected genotoxic chemicals to the damaging effect of higher doses of the same or other agents, is commonly referred to as adaptive response (AR) It has been demonstrated in several cell types as well as in vivo experiments, by measuring chromosomal and ...

A Combined Monitor-Dosimeter for Non-Ionizing Radiation

MTT-S International Microwave Symposium Digest, 2005
The temperature-dependent light-scattering properties of cholesteric liquid crystals and the thermal fade characteristics of pre-irradiated thermoluminescence dosimetry tags are combined in a differential calorimeter configuration to provide measures of present, average and accumulated exposures to non-ionizing electromagnetic radiation.

A Passive Method for Monitoring Non-Ionizing Radiation

MTT-S International Microwave Symposium Digest, 2005
The temperature-dependent light scattering properties of cholesteric liquid crystals are used as both the sensing and indicating mechanism in a calorimetric radiation monitor. The liquid crystals are arranged on two dielectric disks; one is a plain dielectric and the other is metal coated.

EXPOSURE TO NON-IONIZING RADIATION OF PERSONNEL IN PHYSIOTHERAPY

2006
There is a variety of sources of non-ionizing radiation (NIR) in physiotherapy: pulsed magnets, d'Arsonvale devices, equipment for microwave and high frequency therapy, optical sources (UV, IR and visible), lasers. This creates big difficulties to make precise exposure assessment on the workplaces.

Health effects of non-ionized electromagnetic radiation

2008 International Conference on Recent Advances in Microwave Theory and Applications, 2008
Summary form only given. Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes.

Non-ionizing radiation safety: radiofrequency radiation, electric and magnetic fields

Physics in Medicine and Biology, 1992
The static, low-frequency and radiofrequency parts of the electromagnetic spectrum are used in various areas of human activity. Equipment utilizing this energy today is to be found in industry, medicine, commerce and private homes. The author provides a short survey of the biological effects and concentrates on the principal experimental and ...

Effects of Non-Ionizing Radiation on Animals

Non-ionizing radiation (NIR), encompassing electromagnetic fields (EMFs) ranging from extremely low frequencies (ELF) to radiofrequency (RF) and microwave spectra, has become a growing concern due to the proliferation of wireless technologies and electrical devices.
