Very powerful and penetrating, high-energy electromagnetic radiation of shorter wavelength than that of x-rays. They are emitted by a decaying nucleus, usually between 0.01 and 10 MeV. They are also called nuclear x-rays.
Radiation similar to X-rays but higher in energy output.
Part of electromagnetic radiation with the smallest wavelengths and thus the most energy of any wave in the electromagnetic spectrum.
A ray which is shorter than an X-ray and is given off by radioactive substances.
Electromagnetic wave of very short wavelength emitted by radioactive substances. Controlled radiation with gamma rays and rays of other wavelengths is used in medical diagnosis and in the treatment of some skin cancers and other cancers deep within the body.
High-energy electromagnetic radiation released in certain radioactive decays. In medical physics, gamma rays released from excited daughter elements are used for imaging or therapy.
Electromagnetic radiation of wavelengths shorter than X-rays, given off by certain radioactive substances. Gamma rays have greater penetration than X-rays; they are harmful to living tissues and can be used to sterilize certain materials. Carefully controlled doses are used in radiotherapy.
Short-wavelength penetrating electromagnetic rays produced by some radioactive compounds. More powerful than X-rays, they are used in certain radiotherapy treatments and to sterilise some materials.
Short wavelength, highenergy electromagnetic radiation emitted by disintegrating atomic nuclei.
Radiation of the electromagnetic nature discharged by radioactive substances. It exhibits notable resemblances to roentgen rays, yet surpasses both alpha and beta particles in terms of penetration capabilities.
Short-wavelength, high-energy electromagnetic radiation is emitted by radioactive substances, exhibiting a distinct characteristic.
Radiation released by radioactive materials, characterized by a shorter wavelength compared to x-rays.
