Worldwide the maximum acceptable radiation level varies from 10 mW/cm2 to 0.1 mW/cm2. Hoisting and lifting, working at a height and transport. Inappropriate or incorrect use and a wrong design increase the chances of physical harm. Energy moves through the air in various frequencies of electromagnetic waves, called Electromagnetic Field radiation, or EMF radiation. Static magnetic fields cause slight electrical potential differences in blood vessels. However, ionizing radiation from certain levels produces molecular damage that can lead to very serious health problems, such as DNA damage, cancer, and reproductive defects ranging from miscarriages to birth defects and diseases. Here the skin can be burnt. Which rules apply with respect to working at a height? Long-term risks In the infrared area the IR-A area poses the biggest risk (retinal damage and ashen cataract). Artificial parts or aids for the human body such as pacemakers and ferromagnetic implants (limit value 0.5 mT) can be affected. Ionising radiation can cause burns, radiation sickness, and cancer. Excessive exposure mainly poses a risk for the eyes and skin. Research on extremely low frequencies (ELF), specifically in the frequency of electric grids, also focused on the development of cancer, in particular leukemia in children, outcomes of pregnancy (miscarriages, birth weight), child behavior, cognitive function, hormones, neurodegenerative diseases (e.g. Exposure Exposure to electromagnetic fields in this frequency range can warm up exposed tissues because these absorb the radio wave and microwave energy and convert these into heat. Non-ionising radiation does not penetrate deep into the tissues but increases the risk of damage to the skin and eyes. In the particular case of non-ionizing radiation due to its frequency but extremely intense (only intense lasers ), the phenomenon of non-linear ionization appears, therefore, it is also ionizing. Ionizing radiation, which includes ultraviolet rays, X-rays and gamma rays, … Our bodies are exposed to natural radiation every day -- from soil and underground gases to cosmic radiation from the sun and outer space. During work at high temperatures infrared light is emitted, for example during welding, forging and glassblowing, or from heat lamps and plasma sources. Radiation isn't necessarily always dangerous. Read here which measures you can take. Non-ionizing radiation may react with biological tissues through a variety of mechanisms. Most of the studies on radio frequencies have focused on the risk of developing cancer in its various forms, in particular brain tumors and tumors of the acoustic nerve or salivary glands. A key factor in determining the health effects is whether it is chronic or acute. Which personal protection equipment should I use at my work?

As far as we know today, non-ionizing radiation is unable to directly affect genetic material (DNA) because its energy level is not high enough to destroy the bonds between atoms and molecules of body cells. Risks for visible light and infrared light (IR) (0.4 - 1000 μm) It depends on its strength, type and the length of exposure. mercury lamps). and transmitters, microwave ovens, industrial RF heaters, radio and TV antennae, radar installations and mobile phones. Cell Phones and Radio Frequency Energy. Visible light, microwaves, infrared light, are the common sources of non-ionizing radiation. This spectrum is divided into two distinct categories: ionizing and non-ionizing. Radiation is generally classed as either ‘ionising’ or ‘non-ionising’, with the former generally having more energy than the latter. Nevertheless, non-ionizing radiation may affect biological tissues through other mechanisms. Additional health outcomes studied were the effects on: fertility (e.g. The existence of a possible association between exposure to non-ionizing radiation (such as that emitted by mobile phones, domestic wireless phones, wireless communication networks, cellular base stations/antennas, electric grids, etc.) Risks for static fields and extremely low frequency (ELF) fields (0 – 300 Hz) The information is not intended to serve as a substitute for direct consultation with the appropriate professionals. If resonances occur in parts of the body then the damage can increase. For instance, too much ultraviolet (UV) light from lying out in the sun is known to cause some skin cancers; even moderate amounts can cause skin burns. X-rays are a form of ionizing radiation. Instead of producing charged ions when passing through matter, non-ionizing electromagnetic radiation has sufficient energy only for … How do I disconnect items from the power supply? Hoisting and lifting: what should I be aware of? Non-ionizing radiation may react with biological tissues through a variety of mechanisms. The eyes are also sensitive for excessive light. The threshold value for energy absorption, based on the induced current density and the specific absorption rate (SAR, W/kg), is 1 W/kg. All radiation is broken up into two kinds, ionizing, and non-ionizing. Health risks of exposure to non-ionizing radiation--myths or science-based evidence Exposure to EM fields induces body currents and energy absorption in tissues, depending on … At flux densities > 3 mT metal parts can be attracted to the magnetic field. Ionizing radiation directly damages the covalent bonds of your DNA, while non-ionizing radiations create hydroxyl free radicals (OH-), causing indirect damage. 1000 Studies Link Non-Ionizing Electromagnetic Radiation As Dangerous To Mammals.
