Theory of radioactivity
WebbI1 = Intensity with a distance measured as (R/hr or mR/hr) D1 = Distance with an intensity (usually measured in feet) I2 = Intensity without a Distance D2 = Distance without Intensity To solve for Intensity (I2) means that we want to know what the radiation intensity is at a given, second location or known distance (D 2 ). WebbEarly studies of radioactivity relied on measuring ionization power or on observing the effects of radiation on photographic plates. In 1898 French physicists Pierre and Marie …

The SI unit of activity is the becquerel (Bq), equal to one reciprocal second. The radioactive decay of a certain number of atoms (mass) is exponential in time.

WebbRadioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.A material containing unstable nuclei is considered radioactive.Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and …
