Exempel på gamma ray

• Polonium contains especially alpha rays and a few gamma rays. In the case of uranium, the alpha rays have extremely slight penetrating power, and cannot even impress photographic plates. 

• That was the dangerous kind, because both beta particles and gamma rays could penetrate clothing and skin. 

• Natural phenomena such as mass extinctions, supernovae and gamma ray bursters are more problematic for civilization.

• Recent investigations of cosmological gamma ray bursts suggest that these too could cause ozone depletion.

• The exact form of the source modulation and the nuclear-resonant thickness of the resonant absorber determines the shape of the time-differential resonant gamma ray transmission spectrum.

• To my knowledge, gamma ray irradiation has been known to scientists for over 30 years.

• We know all that there is to be known about gamma ray irradiation at the present time.

• The chamber would manipulate the gamma ray into a way that it could be recorded.

• At present, ytterbium is mainly used as a dopant of stainless steel or active laser media, and less often as a gamma ray source.

• This low gamma ray production rate makes it more difficult to find and identify this isotope.

• The atom is not ionised, and the gamma ray continues on, although at a lower energy.

• During this interaction, energy is transferred from the gamma ray to the electron, which is a directly ionizing particle.

• A secondary gamma ray with less energy (hence lower frequency) also emerges from the interaction.

• The neutron can be detected by its capture on an appropriate nucleus, releasing a gamma ray.

• Iridium-192 is also a strong gamma ray emitter.

• Iridium-192 is commonly used as a gamma ray source in industrial radiography to locate flaws in metal components.

• The constituent elements of the sample absorb some of these neutrons and emit prompt gamma rays which are measured with a gamma ray spectrometer.
