The radioactive isotope Na-22 decays through β+ emission. Figure 10.2 shows the decay scheme of Na-22. Figure 10.2. Decay scheme of Na-22. The decay scheme shows that the β+ emission is in 99.94 % of the decays followed by a gamma ray with an energy Eγ1 = 1.27 MeV. The emitted positron will immediately

As can be seen from the figure, there are two gamma ray photopeaks. Gamma Ray Dose Constants. The “Specific Gamma Ray Dose Constant”, sometimes known as the “Gamma Factor”, is the dose rate at a specific distance from a given amount of a photon-emitting radionuclide.

9 Aug 2020 In the experiment, the Na-22 source emits two back-to-back 511-keV gamma lines (The simulated spectrum is supposed to be continuous

8 Oct 2015 One such isotope is sodium-22 (22Na), which decays by positron emission and emits a third γ-ray with 1,275 keV energy in addition to the two Gamma Novae P Peer Reviewed Science Sodium 22 Target We have measured the strengths of low-energy Na22(p,γ)Mg23 resonances directly and As shown in the figure, 22Na causes a distortion in observed gamma spectrum by the sum effect of 1.275 MeV gamma rays and 0.511 MeV annihilation radiation atoms of 235U, where NA = 6.023*10 23 is the Avogadro number. The decay 0. 500.

A naive way I tried is defining two gamma Radioactive source (Na-22)Sodium-22 is the radioactive source which has 11 protonsAnd 11 neutrons and by beta plus it is decay to Neon-22.In general of stable nuclei 6. Decay scheme in general I measured the gamma spectrum of Na-22 with a Ge-spectrometer. Using Genie-2000 software I saw two peaks in the spectrum, 1274 keV (peaksurface 3981±1,74%) and 511 keV (peaksurface 25494±0,68%). (Horizontal axis is divided into channels, each representing an energy band.
