Background radiation.
Solar radiation that is not reflected is absorbed by clouds, the atmosphere and the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%Source: (NASA)
Radiation patients can get near babies if they have been given an external beam radiation. However, if they have been given the injected radioactive isotope, a common treatment for thyroid diseases, they cannot go near babies or even other individuals for that matter.
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
You may be referring to a wide class of radiation known as ionising radiation. Just which parts of this class that should be considered lethal to people is subject to contraversy. Please see the link.
It's the emission of electromagnetic energy from something, not the transfer. That em-radiation could travel for ever across the universe, never interacting with anything ever again and it would still be radiation.________________________________________________________Not all radiation is electromagnetic engery. Electromagnetic energy is transfered by way of photons. Photons are emited through gamma radiation and black body radiation. Nuclear decay of alpha particles and beta particles (which are also considered radiations) are actual particles that have mass, and are not electromagnetic radiation.
About 6% of incoming solar radiation is reflected back into space from the atmosphere and 4% by the surface of the earth.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
ALARA is the concept that is considered to be the cornerstone of radiation philosophy. ALARA stands for "as low as reasonably achievable.:

Ultra-violet radiation, on certain individuals of white skin who are exposed under too much sunlight.

About 26% of incoming solar radiation is reflected back into space from the clouds and atmosphere. Another 16% is absorbed by the atmosphere.Incoming solar radiation: 100%Reflected by the atmosphere: 6% : Absorbed by the atmosphere: 16%Continuing incoming solar radiation: 78%Reflected by clouds: 20% : Absorbed by clouds: 3%Continuing incoming solar radiation: 55%Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51%
Cherenkov radiation is seem by the naked eye is a bright blue it is not considered to be harmful. The Cherenkov radiation is generating from electromagnetic radiation that comes from the speedo of particles traveling.
Personal dosimetry is used to monitor and measure the amount of radiation exposure received by individuals who work with radioactive materials or in radiation-related environments. The purpose is to ensure that radiation exposure remains within safe limits to protect the health and safety of individuals. Dosimetry helps to assess radiation risks, implement necessary safety measures, and comply with regulatory requirements.

An LED TV does emit radiation. However, the amount is very small and not considered harmful. The radiation from an LED television is much less than the radiation that was emitted from older television models.
Radiation of foods, etc, to prolong freshness. Considered to be dangerous.
