frequency of gamma rays?

Answer 1

Gamma rays have a frequency of: 10^18 hertz (cycles per sec)

Answer 2

Gamma Rays are electromagnetic radiation. In Industrial Radiography, the energy of gamma rays is usually expressed in KeV and MeV. Iridium 192 has a relatively soft spectrum of 0.31, 0.47 and 0.6 MeV but Cobalt 60 has 1.33 and 1.17 MeV. Spent nuclear fuel has still higher energies and thus harder gamma rays.

The higher the MeV, the higher the energy and therefore the frequency of the gamma rays. The penetrating power of the radiation is dependent on the energy and the medium.

Answer 3

Anything greater than 3x10^18 Hz. That's 3,000,000,000,000,000,000 cycles per second.
