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
