The most harmful radiation to humans is ionizing radiation, which includes gamma rays, X-rays, and high-energy ultraviolet (UV) radiation. These types of radiation have enough energy to remove electrons from atoms and can damage cells and DNA, leading to serious health effects such as cancer and radiation sickness.
The scientific community has not definitively proven that the low levels of radiation emitted by cell phones are harmful to humans. However, it is recommended to limit exposure by using hands-free devices or speakerphone, and keeping the phone away from the body when not in use.
Radiation can be harmful to humans by damaging cells and DNA, leading to potential health effects such as cancer or radiation sickness. Different types of radiation, such as ionizing radiation, have varying levels of harmful effects depending on factors like dose and duration of exposure. Protection measures, such as shielding and monitoring exposure levels, are important to minimize health risks from radiation.
infrared radiation is invisible to humans
It is a type of ionising electromagnetic radiation. Ionising radiation is radiation composed of particles that individually have sufficient energy (or can liberate sufficient energy) to remove an electron from an atom or molecule, i.e., in this situation humans. It damages the cells of your skin essentially by smashiing into it.
The radiation in smoke detectors, usually in the form of ionizing radiation from americium-241, is very low and not harmful to humans under normal conditions. The radiation level from smoke detectors is well within safety limits set by regulatory agencies.

Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
Gamma radiation.

The ozone layer in the stratosphere absorbs harmful ultraviolet (UV) radiation from the sun. This layer acts as a shield, preventing most of the UV radiation from reaching the Earth's surface, where it can cause harm to living organisms, including humans.
Because it protects us from the suns harmful rays/radiation.
infrared radiation is invisible to humans
It deflects harmful radiation and keeps earth at livable temperatures.

Lack of air, radiation, extreme temperatures.
Yes, humans give off a very small amount of radiation due to the natural radioactive decay of elements within our bodies, such as potassium-40. This radiation is very low in level and not harmful to others.
