If the isotope and dose-rate are known, the activity may be calculated. The method used is extrapolation tables from the 'Handbook of Health Physics and Radiological Health.' A brief tutorial about the three different kind of download (if available): "Download a single setup file": it means that you download an install .exe file; you have simply to execute it to install VA.The setup file will create for you directory and link. Remember that in any case VA is a program "standalone", fully contained in a single executable file without DLL (see next point). Lastly, 137 Cs ranged (1.08±0.26 - 2.97±0.40) Bq.kg -1 with mean of 0.32±0.13 Bqkg -1 .

The K shell conversion coefficient α K of 661 keV gamma transition has been determineto be 0.0976±0.0055, and K/L/M to be (5.66±0.04)/1/(0.260±0.003), which are in good agreement with Rose's calculated values for the M4 transition. The study of beta-decay spectra led to discovery of the neutrino.

RSS-8 Alpha, Beta, Gamma Disc Source Set. Designed for gamma spectroscopy, the RSS-8 contains eight different gamma emitting isotopes covering the entire energy range from 32 to 1333 keV. Also included in the set is a mixed source of Cs-137 and Zn-65 which students may use to identify an “unknown” isotope.

Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles. Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter.

For instance, the available energy in the caesium-137 beta decay is 1176 keV, but in 95 % of the cases it is accompanied by the emission of a characteristic 662 kev gamma in which case the available energy is only 514 keV.

The K shell conversion coefficient α K of 661 keV gamma transition has been determineto be 0.0976±0.0055, and K/L/M to be (5.66±0.04)/1/(0.260±0.003), which are in good agreement with Rose's calculated values for the M4 transition. Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.

emitted by means of beta-ray spectrographs to check these results. Two beta-ray spectrographs were used: a thin magnetic lens spectrograph and a small 180' spectrograph. The spectrographs had been previously calibrated by measure-ments of the spectra of ThB, P", and Cu". (In the case of the small 180' spectrograph the Beta rays and internal conversion electrons from Cs 137 have been studied using a two directional focusing beta ray spectrometer (∂ = 40 cm). Beta rays and internal conversion electrons from Cs 137 have been studied using a two directional focusing beta ray spectrometer (∂ = 40 cm). The characteristic 662 keV peak does not originate directly from 137 Cs, but from the decay of 137m Ba to its stable state. Caesium-137 has a half-life of about 30.17 years.
