The radioisotope 15O (t1/2 = 122 s) is used to measure respiratory function. Patients inhale the gas, which is made by irradiating nitrogen gas with deuterons (2H). Consider a cubical cell measuring 1.24 cm on each edge, which holds nitrogen gas at a pressure of 2.25 atm and a temperature of 293 K. One face of the cube is uniformly irradiated with a deuteron beam having a current of 2.05 A. At the chosen deuteron energy, the reaction cross section is 0.21 b. (a) At what rate is 15O produced in the cell? (b) After an irradiation lasting for 60.0 s, what is the activity of 15O in the cell?

Polonium-210, a naturally occurring radioisotope, is an α emitter, with t1/2 = 138 d. Assume that a sample of 210^Po with a mass of 0.710 mg was placed in a 230.0 mL flask, which was evacuated, sealed, and allowed to sit undisturbed. What would the pressure be inside the flask (in mmHg) at 20 ∘C after 369 days if all the α particles emitted had become helium atoms? Please answer in mmHg, thank you.

If T1 and T2 are independent exponential random variables, find the density function of R=T(2) - T(1). This is for the difference of the order statistics not of the variables, i.e. we are not looking for T2 - T1. It is implied that they are both from the same distribution. I know that fT(t) = λe-λt fT(1)T(2)(t1,t2) = 2 fT(t1)fT(t2) = 2λ2 e-λ​​​​​​​t1 e-λ​​​​​​​t2 , 0 < t1 < t2 and I need to find fR(r). From Mathematical Statistics and...
