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.
Those having very high frequencies such as X-ray and gamma ray are very dangerous.
I would say gamma ray
Radioactive radiation, such as X-rays and gamma rays, is dangerous and can harm, and even kill living things.
Gamma
No. Gamma rays are extremely dangerous to humans and can cause death.
Gamma radioactivity would be the most dangerous because, unlike alpha particles that can be blocked by paper or skin, and beta particles which can be shielded by foil, gamma radioactivity would need a lead shield. Plus gamma radioactivity effects organic material.
"Gamma ray" is the name we give to electromagnetic radiation with the shortest wavelengths, the highest frequencies, and photons with the highest energies. It's the category of radiation past X-rays, and more penetrating and dangerous to living tissues than X-rays are.
Gamma Waves
Radioactive radiation, such as X-rays and gamma rays, is dangerous and can harm, and even kill living things.
Usually for killing cancerous tumors, as in radiotherapy. Sometimes also for medical imaging, as in a gamma camera. Generally, Gamma rays are dangerous to living tissue.
At the highest end of the Electromagnetic Spectrum are wavelengths known as Gamma Waves. Gamma Waves are a unique form of radiation that is highly dangerous to living tissue.
All high frequency radiation e.g. X rays , gamma rays etc. are harmful to living things .
They are harmful to living things because they are higher energy waves.
Gamma-rays are extremely high-energy photons and VERY dangerous. It is the worse form of atomic radiation of the 3 types of radioactive decay, and destroys living tissue and DNA.
alpha radiation is more dangerous than beta or gamma if ingested or inhaled because its power to ionize (or to disrupt atoms) is 20x than that of beta and gamma. but if the source is outside the body or at a distance gamma radiation is much dangerous because it could penetrate thick walls.
Externally, gamma radiation is dangerous because it can penetrate the body. Alpha is most dangerous if ingested.
Death rays. Most types of radiation is dangerous, even the UV that makes it though the atmosphere. However, a human body can cope with a level or incoming radiation. Higher energy rays, such as gamma and x-rays are much more damaging, but fortunately they do not penetrate the atmosphere very well.
uv rays,gamma rays and x rays
No. All things are radioactive, including living things and even humans. All matter (save a few) emits gamma radiation spontaneously.
