It can refer to the fatality rate â the number of deaths per number of cases â or it can mean the number of deaths in total caused by a disease.

This will raise the fatality rate for many infectious diseases, such as tuberculosis, malaria and infectious diarrhea.
Although you may still occasionally hear remarks such as âradon is a hoax!â or âsome radon is good for you,â there is no scientific doubt that exposure to high radon levels can cause lung cancer.lthough you may still occasionally hear remarks such as âradon is a hoax!â or âsome radon is good for you,â there is no scientific doubt that exposure to high radon levels can cause lung cancer.
Radon is a radioactive gas that comes from the natural radioactive decay of radium, which is a natural decay product of uranium.Scientifically, âradonâ is known to be radon-222, the most abundant isotope of the element radon.s a noble gas, radon is colorless, odorless and chemically inert and cannot be detected by human senses. Also, since radon is not chemically reactive with most materials, it will move freely as a gas. Radon has a radiological half-life of 3.8 days, and can move substantial distances from its point of origin.
