this study present several examples of using Excel spreadsheets to and simulate physical phenomena, namely projectile motion, falling motion in The air, wave function particles a one-dimensional box, nuclear radioactive decay. Spreadsheets are used analyze the projectiles with without resistance, objects different terminal velocities, graphs functions probabilities values n, i.e. n=1 n=4, decay...

The proposed model describes in a quality way the process of tumor-imaging radiopharmaceutical 99mTc-MIBI distribution with taking into account radiopharmaceutical accumulation, elimination, and radioactive decay. The dependencies of concentration versus the time are analyzed. The model can be easily tested by the concentration data of the radioactive pharmaceuticals in the blood measured at ea...

Low counting experiments (search for double β decay and dark matter particles, measurements of neutrino fluxes from different sources, search for hypothetical nuclear and subnuclear processes, low background α, β, γ spectrometry) require extremely low background of a detector. Scintillators are widely used to search for rare events both as conventional scintillation detectors and as cryogenic s...
