Scientists generally agree it is not harmful except if the intensity is enough to cause heating of the tissues. For example a microwave cooker produces enough heat to cause harm, which is why the door cannot be opened while it's switched on. However it is a controversial subject that includes use of cell phones and other radio frequency transmitters. Today the focus is not on whether it is harmful, but how much and at what levels it is harmful.

Why is radiation harmful to both living and nonliving things?
This depends on the kind of radiation. Most electromagnetic radiation is harmless (e.g. broadcast radio) or only very slightly harmful (e.g. microwave, infrared, and visible light can cause heating of materials and thus thermal changes). However very high energy electromagnetic radiation (e.g. ultraviolet, x-ray, gamma ray) and the particulate radiation of radioactive decay and cosmic rays has enough energy to break the bonds holding molecules together, causing chemical changes.
What are some positive and negative things about ultraviolet light?
UV rays are electromagnetic waves have shorter wavelength than that of visible light(10nm to 400nm) It can cause chemical changes, hence causes many substance to glow It is non ionizing radiation It can cause damage to living beings(harmful to humans) and is blocked by ozone layer It may leads to cancer It produces heat in surface of earth Used to prevent counterfeiting UV rays are used for wireless communication also
The Earth's magnetic field helps protect living things from?
From solar radiation and cosmic rays
What harm can radiation can cause to living tissue?
When radiation strikes complex biological molecules such as proteins or nucleic acids ,it may fracture the molecules and prevent their proper functioning.This can result in loss of cell vitality,decreased enzyme activity, initiation of cancer and genetic mutations.
What are the Two harmful things the answer?
Two things that are harmful
Which types of EM radiation can be dangerous to living things?
Ionizing radiation, such as X-rays and gamma rays, can be dangerous to living things because they have enough energy to remove electrons from atoms, causing damage to cells and DNA. Ultraviolet radiation, particularly UVB and UVC, can also be harmful as they can cause sunburn, skin cancer, and other health issues with prolonged exposure.
What kind of waves are harmful to living things?
All high frequency radiation e.g. X rays , gamma rays etc. are harmful to living things .
Is it true nitrogen gas is needed to help protect living things from harmful radiation?
Nitrogen gas does not directly protect living things from harmful radiation. The Earth's atmosphere, which is about 78% nitrogen, plays a role in filtering out some of the harmful ultraviolet radiation from the sun. However, the ozone layer is the primary atmospheric component responsible for shielding living things from the most harmful UV rays.
Why is the ozone layer important to all living things?
Ozone layer reflect UV radiation. UV radiation is very harmful
What causes of mutation in living organisms?
Many things: ionizing radiation, free radicals, various chemicals, copying errors, retroviruses, etc.
Which type of radiation-alpha beta or gamma- is most dangerous to living things?
Ionizing radiation can be dangerous to living things, as it upsets the chemistry in living cells by breaking covalent bonds between atoms. Even if the radiation is not ionizing, such as in neutron flux, damage can be done there as well, due to activation processes that change the chemical identity of atoms.
What layer is located in the stratosphere and protects living things from getting harmful radiation?
the oz-zone layer :)
Which electromagnetic wave is most harmful to living things?
Ultraviolet (UV) radiation is considered the most harmful electromagnetic wave to living things as it can cause damage to skin cells, DNA, and increase the risk of skin cancer.
What are the advantages and disadvantages of microwave radiation for heating a room?
The advantages and disadvantages of microwave radiation is that it is extremely harmful to humans and living things in general however it is very useful.
Electromagnetic waves that are harmful to living things are?
Ultraviolet (UV), X-ray, and gamma-ray electromagnetic waves are harmful to living things because they can cause damage to cells and DNA, leading to health issues such as skin cancer and radiation sickness. It's important to limit exposure to these types of electromagnetic radiation to protect our health.
What is nonionizing radiation?
Nonionizing radiation is a form of electromagnetic radiation that does not have enough energy to remove electrons from atoms or molecules. Examples include visible light, radio waves, microwaves, and infrared radiation. Nonionizing radiation is generally considered less harmful than ionizing radiation, although prolonged exposure to certain types like UV radiation can still pose health risks.
Why is ionizing radiation dangerous?
Ionizing radiation is dangerous because it has enough energy to remove tightly bound electrons from atoms, creating charged particles called ions. These ions can damage cells and genetic material in the body, leading to potential health risks such as cancer and other serious health effects. Prolonged or high doses of ionizing radiation can cause severe harm to living organisms.
