The emission of the X-ray and/or Auger electrons follows EC, and therefore, the EC decaying radionuclides can be determined by X-ray spectrometry of emitted X-rays or by liquid scintillation counting (LSC) of the Auger electrons.

How do you determine decay type?

In terms of decay types, beta decay is predicted by looking at an isotope's neutron to proton ratio. Alpha decay will occur frequently in elements with atomic numbers greater than 83, and gamma decay will occur when a nucleus is an excited state.

What is EC in decay?

Electron capture is the primary decay mode for isotopes with a relative superabundance of protons in the nucleus, but with insufficient energy difference between the isotope and its prospective daughter (the isobar with one less positive charge) for the nuclide to decay by emitting a positron.

What is evidence of radioactive decay?

the alpha particle is emitted with only 3.3 MeV of energy. By measuring the energy of the alpha emitted, we can identify which decay process has occurred. An example spectrum for alpha decay might look like the one in the figure. Alpha decay only takes place in nuclei with large numbers of neutrons and protons.

Is electron capture radioactive decay?

Electron capture is the radioactive decay process by which an atom's inner orbital electron is absorbed within the nucleus followed by conversion of a proton to a neutron and emission of a neutrino (ve) 1.

Why do scientists analyze radioactive decay?

Radioactivity can cause damage in materials and in plant, animal, and human tissue. Scientists and engineers use radioactivity as a source of heat for satellites, for medical imaging, for targeted cancer treatments, for radiometric dating, and for research into the laws of nature and the origin of matter.

What determines the type of decay a radioisotope will undergo?

What determines the type of decay a radioisotope undergoes? "The neutron-to-proton ratio in a radioisotope determines the type of decay that occurs. "

How do scientists think gamma rays are produced?

They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.

How do you distinguish between neutrino and antineutrino?

Both neutrino and antineutrino are two subatomic particles. However, the key difference between antineutrino and neutrino is that the neutrino is a particle whereas the antineutrino is an antiparticle. Moreover, a neutrino-antineutrino collision will annihilate both particles and produce two photons.

How is radioactive decay measured?

Geiger counters are commonly used to measure the amount of radioactivity, but there are other types of detectors that may be used.
