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.

What causes earth's surface to heat?
The sun ray's are most responsible for Earth's surface temperature.
What country did earth hour start in?
earth hour started in New Zealand because it is the first to get sun ray.
Before the suns ray can reach earth surface they have topass through the?
the atmosphere
The hottest objects with temperatures in the millions of degrees Kelvin give off most of their radiation in which part of the electromagnetic spectrum?
X-ray part
What is the half value layer for cobalt-60?
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?
What would happen to earth if it got hit by a gamma-ray burst?
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.
What if earth were hit by a gamma ray burst?
The earth would be completely destroyed.
Do gamma ray bursts emit light faster than the speed of light?
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
Uses of technetium?
Its short-lived gamma ray-emitting nuclear isomer-technetium-99m-is used in nuclear medicine for a wide variety of diagnostic tests.
What is an x-ray photon?
A photon is a packet of electromagnetic radiation. An X-ray photon is one of these with a wavelength in the range of 0.01 to 10 nanometers.
Can you think of any objects or processes outside the solar system that might affect the earth?
A gamma ray burst would certainly affect earth, depending on how far away it is. It could come from outside the solar system.
Which ray is the strongest?
Gamma Ray
Will a gamma ray burst end the world?
There has been some speculation that a gamma ray burst has affected life on earth at one or more intervals in the past. And it is possible for it to happen in the future. For a gamma ray burst to destroy earth, the source would have to be moderately close, and because one characteristic of the gamma ray burst is that the emitting body directs two separate "rays" out in opposite directions. We'd have to be exactly in the wrong place at the wrong time and end up on an axial alignment with the gamma ray beam. As the beam is of short duration, the earth would shield a portion of life from its direct effects, but the destruction (ionization) of our atmosphere by the high radiation could burn the entire surface of the planet. Even on the "back side" away from the direction the beam originated in. This could happen, but will it happen? It's an event of low probability. Not that anyone will be spared if we "win the lottery" and get tagged.
Is gamma ray used in lasers?
No gamma rays can't effect solid objects, laser stands for light amplification of stimulated edition of radiation. Hope that helps!
Why do we use gamma ray machine?
We use a gamma ray machine to find out where the gamma rays are and where they are pointed to. We also use these machines to study a gamma ray.
What would happen if a gamma ray burst hit the earth?
The atmosphere would be fried and the Earth would disentegrate.
What do we use gamma ray for?
We use Gamma Ray to make Hulk
