A geiger-muller tube is a type ofgas-filled radiation detector. It candetect particles like X-rays, alphaparticles and beta rays (electrons).This is useful in quantizing theactivity of a radioactive source ordetermining if an area containingradioactive material is safe toenter. Assuming that you haveone mole of gas, if a geigercounter is filled with 9502 Pa ofargon gas at room temperature (T= 21.1 C), what is the density ofthe gas in this geiger tube?

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. (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 moment…

2. Consider two gamma radioactive sources: S1 has activity 50 µCi (micro-Curie) and S2 has activity 25 µCi (micro-Curie). They are separated by 1 m. Assume that both sources are pointlike. s1 S2 1 m a) At which location along the dashed line passing by the two sources is the flux due to S1 equal to the flux due to S2 ? b) What is the gamma fluence in that location in a time interval of two minutes ?
What is the half-life of a radioactive isotope if the activity of a sample drops from 6,080 cpm to 190 cpm in 21.0 min? Answer needs to have significant figures. I got 4.2 min as my answer but am told it is wrong.
Experimentally, it is found that natural potassium emits 31 beta particles per second per gram and 3.4 gamma rays per second per gram. With this data, determine the half- life period of K40. (The isotopic concentration of K40 is 0.0118% .)
Radioactive element AA can decay to either element BB or element CC.The decay depends on chance, but the ratio of the resulting number of BB atoms to the resulting number of CC atoms is always 2/1.The decay has a half-life of 8.00 days.We start with a sample of pure AA. How long must we wait until the number of CC atoms is 1.50 times the number of AAatoms?
One method for determining the age of ancient objects is by radiocarbon dating. Natural processes convert nitrogen to Carbon-14, a radioactive isotope with a half-life of 5730 years. When they are alive, animals assimilate Carbon-14 through the food chain. When an animal dies, it stops replacing its carbon and the amount of Carbon-14 decays exponentially. (a) Suppose the minimum detectable amount is 0.1% of the initial amount. What is the maximum age of a fossil that we could date using Carbon-14? (b) Suppose we wanted to date a fossil that was potentially 70 million years old. A radioactive isotope with what half-life would be required?
