Show affiliationsThe isotope 222Rn belongs to the 238U decay chain and can be obtained from natural mineral sources. The fact that radon is a gas and its radionuclide daughters get implanted on surrounding materials allows a set of different experiments in radiation physics. These experiments range from isotope decay time measurement to alpha, beta and gamma spectroscopy. To solve the radioactive decay chain equations, a simple iterative method is used as an alternative to the exact analytical solution.
