Not exact matches

Soon thereafter, Ernest Rutherford and Paul Villard identified three different kinds of radiation, dubbed alpha, beta, and gamma rays, emitted by radioactive compounds.

Some black holes do this conspicuously, releasing outbursts of gamma rays and X-rays every time they feed, while others are «closet eaters» that emit very little radiation at feeding time.

The back end of the nuclear fuel cycle, mostly spent fuel rods, often contains fission products that emit beta and gamma radiation, and may contain actinides that emit alpha particles, such as uranium - 234, neptunium - 237, plutonium - 238 and americium - 241, and even sometimes some neutron emitters such as Cf.

The nebula contains a pulsar in its centre which rotates thirty times per second, emitting pulses of radiation from gamma rays to radio waves.

The intensity of Cherenkov radiation emitted by the particle shower produced by the gamma ray is proportional to the gamma ray's energy, whereas the geometry of the shower betrays its direction of origin.

When these gamma rays reach the Earth's atmosphere they are absorbed, producing a short - lived shower of secondary particles that emit weak flashes of bluish light known as Cherenkov radiation, lasting just a few billionths of a second.

Radioactive materials, by their very nature, emit gamma rays or other distinctive radiation signatures.

However, rather than emitting violent bursts of gamma - ray radiation, like blazars, Seyfert galaxies are known for their strong ultra-violet emissions.

His idea was to use the High - Altitude Water Cherenkov observatory — made up of 300 water tanks on a Mexican mountaintop — to detect gamma radiation produced when charged particles emitted by pulsars interact with the gas between stars.

Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand - born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays in sequence of their ability to penetrate matter.

As these blobs of high - speed matter ram into slower blobs of material emitted previously in the exploding fireball, shockwaves are created that generate the observed gamma - ray radiation.
