A beta ray is incident normally on a 0.35 cmthick lead slab (density = 11.4 g/cm³) lies onthe top of Lucite slab (density = 1.19g/cm). The beta rays emerge from the leadslab with an energy T1=3.69 MeV.The range R (in g/cm2) of the electrons isrelated to the kinetic energy T (in MeV) bythe following:Lucite:R=0.334T1.5Lead:R=0.426TTLead0.35 cmT1d.LuciteWhat minimum thicknessof Lucite (in cm) needed tostop the beta rays fromChoose... +emergina the slah?

Physics Fluorodeoxyglucose (FDG) is a radioactive tracer element that is used for PET (Positron Emission Tomography) scans. The half-life of FDG is about 110 minutes. Given that a patient was injected with FDG to get a PET scan, what is the probability of the FDG not yet being eliminated from their body after 3 hours has passed?

Smugglers. Rumor has it that a company has been smuggling gold out of the country using sealed, cylindrical barrels with hollow walls. They pour molten gold into the hollows, and then fill the remainder of the barrel's internal volume with packing peanuts. The total mass of the gold-walled barrel was designed so that it exactly matches those used to transport a volatile chemical that cannot be exposed to air (and therefore the barrel cannot be opened and checked). The X-ray machine usually used to screen containers is suspiciously damaged and not available. TUL (a) There are 20 barrels total, and they are all identical: mass m = 50.0 kg, height h = 1.2 m, and diameter D = 0.25 m. How do you determine which ones have walls filled with gold (and are essentially hollow on the interior except for packing peanuts) and those completely filled with the volatile chemical (a tightly-packed powder) where the mass is uniformly distributed? Hint: apply the concepts of moment of inertia. Is the…

Given: Nc = (2.51x1019)(mn/mo)3/2 (T/300)3/2 Nv = (2.51x1019)(mp/mo)3/2 (T/300)3/2 and ni = (NcNv)1/2 e(-Eg/2kT) show that: ni = (2.51x1019) ((mn/mo) * (mp/mo) )3/2 e(-Eg/2kT)
Applying x-rays for diagnosis or therapy requires a good understanding of the effects the radiation causes in biological tissue. A lead apron that would stop 3⁄4 of the radiation would already provide passable protection. Find thickness of the apron, if lead mass attenuation coefficient for a radiationsource with an energy of 140 keV is μm = 2.32 cm2/g. Density of lead ρ = 11.35 g/cm3

Alpha particles of kinetic energy 6.9M V are incident at a rate of 3.1x 10" per second on a copper foil of thickness 3.1 x 10-m. A circular detector of diameter 1.0cm is placed 13cm from the foil at an angle of 30° with the direction of the incident alpha particles. At what rate does the detector measure scattered alpha particles? (The molar mass of copper is 63.5 and its density is 8.9em-)
