The radioisotope ¹⁵O (t_1/2 = 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-λt1 e-λt2 , 0 < t1 < t2 and I need to find fR(r). From Mathematical Statistics and...
