Additional Problems
As shown in figure 1, a beam of particles is fired at a stationary target. The resulting nuclei from this collision are highly unstable, and decay almost immediatebly into more stable daughter nuclei. During this decay, charged particles are emitted, which curve in the magnetic field within the detector (in this case, the field is pointing out of the page). Each of these decay particles are collected by the detector and their energies are measured, producing the graph shown in figure 2. What type of decay are the unstable nuclei undergoing? A) α decay B) β- decay C) β+ decay D) γ decay
A radioactive sample has an activity of 1.5x10 8 Bq when it has 2.7x1014 nuclei. What is the half life of this radioactive sample?
After the Chernobyl meltdown in Ukraine in 1986, some 2,000 km  2 of Belarus was covered in cesium-137 with an activity of about 1500 Bq/m2. Cesium-137 decays with a half life of about 30.17 years into Barium-137, which is stable. In 2006, when local physicists collected samples of soil in this part of Belarus to test for radiactivity, what activity of cesium-137 would they measure?
Cesium-137 undergoes β- decay, decaying into barium-137. Measurements of the emitted electrons show that the maximum electron energy is 1.176 MeV. If in some β- decay of cesium-137, the emitted electron has a kinetic energy of 0.284 MeV, what is the energy of the emitted neutrino? Consider the mass of cesium-137 to be 127.528 GeV/c2, the mass of barium-137 to be 127.527 GeV/c2, the mass of the electron to be 0.511 MeV/c2, and the neutrino to be massless.
A radioactive nucleus, X1, decays into a second radioactive nucleus, X 2. The halflife of X1 is 30.4 min, and the halflife of X 2 is 2.5 min. If a radioactive sample begins with 5 g of X 1 and 10 g of X2, how many grams of X 2 will there be after 5 minutes?
