This question hasn't been answered yet Ask an expert. Show transcribed image text. Expert Answer (0.3 MeV or 0.318 MeV on the Decay Scheme) corresponds to the strongest transition (highest emission probability) whereas the second corresponds to the highest endpoint energy (1.5 MeV or 1.492 MeV on the Decay Scheme). Additional transitions are indicated through the use of dots. The excited states of the daughter Cs-137 is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters.

Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137.

In larger amounts, Cs-137 is used in medical radiation therapy devices for treating cancer; in industrial gauges that detect the flow of liquid through pipes; and in other industrial devices to measure the thickness of materials, such as paper, photographic film, or sheets of metal.

Beta decay of Cs-137 – and other nuclei Fig. 3 below gives a quite detailed view of the decay. Further details on the decay will be mentioned below. Fig. 3: decay scheme for Cs-137 As shown in fig. 3 94,7% of beta-minus decays ends in the exited state h 11/2-, and 5,3% goes to the ground state d 3/2+ of the Ba-137 nucleus.

Elemental Cesium has a low melting point (28.5°C, 83.3°F) and so is most commonly supplied in the form of insoluble powders or ceramic microspheres doubly encapsulated in stainless steel tubes 137 Cs decay from 1993-98 (NSR) Decay properties: Mode Branching (%) Q-value (keV) b-100: X-rays from 137 Cs (30.07 y 3) E (keV) I (%) Assignment; 3,954 : 0.0143 Cs-137 is a long-lived parent nuclide which has a half-life of 30.07 years and decays by the emission of beta radiation into the stable isotope Ba-137. This transition is completed either by direct conversion into stable Ba-137 (5.4 %) or via the metastable energy state of Ba-137m (94.6 %). Cs 137 decays by beta- emission (T=30.174y, Δ= -86.5607 MeV) to 56 Ba 137 (Δ= -87.7367 MeV) with the emission of the following radiations: β-: 1.176 Mev; max 7% 0.514 Mev; max 93% γ: 0.662 MeV; 85% The isotope of cesium, 55Cs137 (also written as Cs-137) has an interesting decay scheme. As shown in Figure 1 below, Cs-137 can decay directly to 56Ba137 via beta decay, releasing an energy of 1.18 MeV. However, only 8 % of the decays proceed that way. The great majority of the Cs-137 nuclei decay in a two step process, first with a beta decay to Ba-137m, which is an excited state of 56Ba137. The decay scheme is internally consistent and essentially complete since the total decay energy computed by RADLIST is 1174 (3) keV compared to the Q value of 1175.63 (17) keV, a difference of 1.8 (28) keV.
