Gamma rays are extremely high energy electromagnetic radiation. The source of gamma rays is nuclear "change" like radioactive decay. Radioisotopes, which are either the natural or artificial radioactive isotopes of elements, occur in river deltas, granite, some older paints, some older ceramics, nuclear waste, and specifically irradiated materials that have been made radioactive to be applied to medical devices (like 60Co "pencils" used for medical treatment) or industrial imaging or irradiation sterilization equipments.
The sun ray's are most responsible for Earth's surface temperature.
earth hour started in New Zealand because it is the first to get sun ray.

I would not use Co-60 for shielding. Did you mean, "What is the half value layer for some shielding (XXXXXXXX) using Co-60 as a source of gamma ray energy?
Gammy ray bursts occur about once per day.
It showed that most gamma ray bursts come from other galaxies, not our own. This means that gamma ray bursts must be extremely powerful.
Earth gets hit every day by gamma-ray bursts - from far, far away. Depending on how near the gamma-ray burst is, it may cause some serious damage.
it means gamma ray bursts
Long Gamma ray bursts
When a star goes supernova it releases a bursts of energy (which is also radioactive) that shoot out from the core. Gamma ray bursts have intense radiation and travel so quickly that if one were to hit earth we would get no warning until it hit us and everything would be vaporized. There is a dying star close to earth and right now at any moment it could go supernova and the worst part is its release of energy is aimed right at us. Gamma ray bursts also form when 2 neutron stars collide or when a neutron star collides with a black hole.
neutron stars and black holes
Gamma ray bursts emitting light! What is meant by this? Any way gamma ray coming out of a radioactive nucleus is also an electromagnetic radiation as light but with very much higher frequency. Gamma ray also travels with the same speed as light does. According to Einstein's theory of relativity, no radiation can travel with a velocity higher than that of light
A gamma ray burst results from an extremely energetic implosion/explosion, as in supernovae or hypernovae events, or the less likely possibility of the combination of 2 neutron stars.
There is no known author named Seth Digel as of now.
Lisa Kewley studied cosmic rays and gamma-ray bursts.
