Gamma-rays can be used to treat cancer, and gamma-ray bursts are studied by astronomers. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. Gamma rays and X-rays can ionize or remove electrons from an atom. What gamma rays are and their sources, and the dangers and uses of gamma rays. Even in low doses they can alter the DNA in the cell and result in changed metabolic functions of the cell. Both x-rays and gamma rays are forms of high-frequency ionizing radiation, which means they have enough energy to remove an electron from (ionize) an atom or molecule. X-rays and gamma rays can cause a number of other problems besides cancer. They can even cause cancer. Ionized molecules are unstable and quickly undergo chemical changes.
Electromagnetic (EM) radiation is transmitted …
Gamma rays are the most penetrating of the radiations. Gamma ray bursts are the most energetic explosions in the Universe, outshining the rest of their entire galaxy for a moment. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. A radio photon doesn't have much energy and doesn't travel through matter well (that's why you don't pick up radio well in a tunnel). It cannot be said that a particular thickness of a material can absorb all gamma radiation.
Radioactive decay, lightning strikes and nuclear explosions emit gamma rays. Gamma rays are dangerous because they have a high energy to break bonds. It cannot be said that a particular thickness of a material can absorb all gamma radiation. What problems occur depend upon the radiation dose, the timing of the exposure, and what areas of the body are exposed. The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves.
Alpha particles are the least dangerous in terms of external exposure.
Gamma rays are the strongest from of radiation. Studies have found out that X-rays …
Gamma ray bursts are the most energetic explosions in the Universe, outshining the rest of their entire galaxy for a moment. Because gamma rays are such a high-intensity, ionizing form of radiation, they pass through normal protections, such as skin, clothing, foil and goggles.
The reason gamma-rays are more harmful then radio waves is because light can be thought of as particles (photons) as well as electromagnetic waves. Only high-mass shielding, such as lead, can stop them. Each particle contains a pair of neutrons and a pair of protons. This is what makes nuclear radiation so dangerous. Gamma rays are the most penetrating of the radiations. Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays. Answer to: Why are gamma rays dangerous?
So what are gamma rays? So, it stands … This is why it is not advisable for pregnant women to be exposed to X-rays. Radiation sickness is the cumulative effect of all this damage on a human body that's been bombarded with radiation. Ionizing radiation absorbed by human tissue has enough energy to remove electrons from the atoms that make up molecules of the tissue and may thus cause cell damage. X-rays, gamma rays and UV light can damage living tissues with radiation, and microwaves can cook them.
