Are electromagnetic waves harmful to cells?
Unlike high-energy (ionizing) radiation, EMFs in the non-ionizing part of the electromagnetic spectrum cannot damage DNA or cells directly. Some scientists have speculated that ELF-EMFs could cause cancer through other mechanisms, such as by reducing levels of the hormone melatonin.
How is electromagnetic radiation harmful?
Ionizing radiation can be harmful because it can break chemical bonds and change the molecular and chemical structures of various substances, including human tissue. Overall, a person is more likely to experience damage if they are exposed to high levels of radiation over a longer period.
How does electromagnetic radiation affect our lives?
Exposure to low frequency fields that are strong enough can lead to dizziness, seeing light flashes and feeling tingling or pain through stimulation of nerves. Exposure to radiofrequency fields that are strong enough can lead to heating of body tissue, and result in damage to tissues and organs.
What are the effects of electromagnetic radiation on living things and environment?
For example, high energy microwave radiation at frequencies from 300 MHz to 300 GHz can be carcinogenic and cause thermal effects, increasing the temperature of exposed organisms. On the other hand the same type of microwave radiation at lower frequencies from 100 kHz to 300 MHz has no such effect.
What are the benefits of electromagnetic radiation?
These include nerve regeneration, wound healing, graft behavior, diabetes, and myocardial and cerebral ischemia (heart attack and stroke), among other conditions. Preliminary data even suggest possible benefits in controlling malignancy.
What emits electromagnetic radiation?
Many household appliances produce electromagnetic fields: low consumption light bulbs, television and computer screens, electric radiators and even electric blankets. All of these common objects emit electric or electromagnetic fields and / or function by using them.
How can electromagnetic radiation affects human and environment?
For example, high energy microwave radiation at frequencies from 300 MHz to 300 GHz can be carcinogenic and cause thermal effects, increasing the temperature of exposed organisms. On the other hand the same type of microwave radiation at lower frequencies from 100 kHz to 300 MHz has no such effect.
What are the harmful effects of electromagnetic radiation to humans and the environment?
In 2011, the WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.
Is electromagnetic radiation beneficial or harmful?
Evidence for cellular effects of electromagnetic fields. The general opinion is that there is no direct evidence of hazardous effects on human health incurred by low-frequency radiofrequency waves. Studies at the cellular level, which uses relatively higher frequencies, demonstrate undesirable effects (10-11).
