The decay process takes time and there is value in being able to express the rate at which a process occurs. A useful concept is half-life, which is the time required for half of the starting material to change or decay. Half-lives can be calculated from measurements on the change in mass of a nuclide and the time it takes to occur.

There is evidence that the effects of small doses of radiation are cumulative, at least to some degree, and that there is no lower limit to the dose which can cause some damage.

It explains background radiation, particularly from radon gas, its link to increased lung cancer risk for smokers, and emphasizes the importance of testing homes for radon levels. Additionally, it suggests affordable methods to mitigate radon exposure in residential areas.
