A radioactive sample decays with an average-life of 20 ms. A capacitor of capacitance 100 µF is charged to some potential and then the plates are connected through a resistance R. What should be the value of R so that the ratio of the charge on the capacitor to the activity of the radioactive sample remains constant in time?

Ionizing radiation enters a Geiger tube with 1.45 MeV of energy. As the radiation passes through the tube, all of this energy goes into creating ion pairs and each ion pair requires 30 eV of energy. (a) If an applied voltage sweeps these ions out of the gas in 1.10 µs, determine the current (in A). 1.19e-8 X What is the definition of current? How many electronic charges constitute an ion pair? How can you determine the number of ion pairs created? A (b) Since the applied voltage in the Geiger tube accelerates these separated ions, creating other ion pairs in subsequent collisions, the actual current is greater than that determined in part (a). If this effect multiplies the number of ion pairs by 880, determine the actual current (in A). 1.05e-6 X How is the increase in current related to the increase in number of ion pairs? A
Q7. A 50 µCi source emitting 5-MeV alpha particles is suspended between the palates of a large gas ionization chamber. If the emitted alpha particle loses all its energy in the chamber gas, calculate the current measured at the output. Assume that the average energy to create an ion pair in the gas is 34 eV and that all the charges produced in the chamber are collected.
Suppose a particle of ionizing radiation deposits 1.0 MeV in the gas of a Geiger tube, all of which goes to creating ion pairs. Each ion pair requires 30.0 eV of energy. (a) The applied voltage sweeps the ions out of the gas in 1.00 µs. What is the current? (b) This current is smaller than the actual current since the applied voltage in the Geiger tube accelerates the separated ions, which then create other ion pairs in subsequent collisions. What is the current if this last effect multiplies the number of ion pairs by 900?
