FAQ:

Q: What is the unshielded gamma ray dose-equivalent rate at 1 meter?

A: (After Unger and Trubey ORNURSIC-45 1981) The unshielded gamma ray dose-equivalent rate at 1 meter from a point source, i.e., the specific gamma ray dose constant, is a useful quantity in radiation protection applications. An extensive

Q: What is the difference between a gamma ray and an X-ray?

A: Terminology varies between scientific disciplines. In astrophysics gamma rays are conventionally defined as having photon energies above 100 keV and are the subject of gamma ray astronomy, while radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy.

Q: What is the energy range of gamma rays from radioactive decay?

A: Gamma rays from radioactive decay are in the energy range from a few kiloelectron volts (keV) to approximately 8 megaelectronvolts (~8 MeV), corresponding to the typical energy levels in nuclei with reasonably long lifetimes. The energy spectrum of gamma rays can be used to identify the decaying radionuclides using gamma spectroscopy.

Q: What are some rare terrestrial natural sources of gamma rays?

A: Some rare terrestrial natural sources that produce gamma rays that are not of a nuclear origin, are lightning strikes and terrestrial gamma-ray flashes, which produce high energy emissions from natural high-energy voltages. Gamma rays are produced by a number of astronomical processes in which very high-energy electrons are produced.
