Lets start with some background about the different types of Electromagnetic radiation. Electromagnetic radiation is a form of energy produced by various electromagnetic processes. There are two types of electromagnetic radiation, visible light and the invisible ones such as radio waves, infrared light and X-rays.
There are certain types of electromagnetic radiation that can be harmful to us. You may not be fully aware of it but on a daily basis we use objects and appliances that give off such energy that may potentially be damaging to us. Examples of hazards of electromagnetic radiation of which could be cell phones, power lines and transformers. As we invent new wireless technologies we introduce future new hazards of electromagnetic radiation.
Possible effects of EM Radiation exposure & Hazards of Electromagnetic Radiation
Microwave radiation is used for communication, radar and even cooking. Long-term exposure to this type of radiation can cause cataracts, blisters on the skin, sterility and microwave auditory effect, which is hearing buzzing or microwave pulses. Since mobile phones emit microwave radiation, studies show that it affects part of our brain because we normally hold it close to our head whenever we use it.
Infrared is commonly emitted by heated objects. High levels of infrared emission could cause Glassblower’s cataract, which can be observed on welders who do not use tinted glasses when working. Common examples of objects that emit infrared are remote controls, thermal imaging cameras for medical purposes and night vision, burglar alarms, electric heaters, space telescopes and many more.
Ultraviolet is, of course, connected to sunlight. Overexposure to it can cause sunburn, cataracts, melanoma, wrinkles, freckles, liver spots and damage to the cornea. Other sources of ultraviolet radiation are tanning lamps and beds, arc welding, mercury vapour lamps, industrial processes, and medical and dental practices.
X-rays, as we know, are used for medical imaging and skin cancer treatment. However, exposure to this kind of radiation can damage or kill our cells, increase our risk of developing certain types of cancer such as myeloma and thyroid cancer, cause mutation and genetic damage, and even affect an unborn child.
Gamma rays come from four possible nuclear reactions: fusion, fission, alpha decay and gamma decay. This type of radiation is commonly used in industries such as mining, food, refining and paper. Gamma rays are also used to scan boxes or objects for security purposes. Since gamma rays can kill organisms, it helps sterilise medical equipment and remove harmful bacteria from food. However, it also goes without saying that gamma rays can damage or worse, kill our cells.
Studies show that gamma rays can help treat cancer, but they can also cause certain types of cancer. Aside from that, it can lead to genetic and tissue damage. Short exposure can cause radiation poisoning and large doses of gamma rays can cause diarrhoea, headache, hair loss and delayed healing.
Getting your products EMC tested
It is important that companies that manufacture or import appliances, equipment, industrial machines and electronic objects for sale or distribution seek electromagnetic compatibility testing, radio performance and human exposure testing through an accredited EMC testing laboratory.
These labs offer certification, compliance and approval services. Qualified and highly-trained engineers test and observe the electromagnetic signatures and magnitudes to determine if the levels of electromagnetic radiation is to an acceptable defined local or international standard limit. These sets of tests determine EMC compliance and/or human exposure compliance to an acceptable level of performance relative to the required market and also ensure that the products meet the electromagnetic compatibility requirements and do not adversely interfere with other devices or appliances in the near vicinity.
EMC Bayswater provides efficient and cost-effective compliance solutions to achieve your global certifications so you may be confident in selling, importing or exporting various products in your desired markets.
