3 A Cs-137 source, with activity Fig. (4i) Energy spectrum of the scattered photons at 120 degrees. The yield of caesium by uranium fission is also analyzed. The problem of hermetic sealing of the sources is discussed and a complete nomenclature of all the sources manufactured in the USSR are listed, their size and activity also being indicated. In conclusion a comparison of Co 60 and Cs 137 sources is made.

Ba133 Gamma Spectrum 133Ba (Barium) There are 33 known isotopes of Barium, of which 133Ba is the most stable, it has a half life of 10.5 years, and emits a whole range of gammas, some which can be readily identified with a sodium iodide detector, and many that require higher resolution to see.

[Ba-133]. [Co-57]. [97% Enriched Uranium disk]. [97% Enriched Uranium The analysing of 137Cs content in the soil is done by gamma spectroscopy. Caesium (Cs) is the heaviest alkali metal (atomic number of 133), that occurs in Caesium-137 has a radioactive half life of 30.2 years. It decays by beta Effective half-life of Cesium-137 in humans is approximately 110 days (ICRP Pub .78).

This particular isotope of caesium is both a beta and gamma emitter. Exposure to Cs-137 can increase the risk for cancer because of the presence of high-energy gamma radiation. Internal exposure to Cs-137 through ingestion or inhalation allows the radioactive material to be distributed in the soft tissues, especially muscle tissue, which increases cancer risk.
