So the answer is YES to both questions, because the radiation is much more dangerous than the presence of xenon and this risk is …
Half-life (symbol t½) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential (or, rarely, non-exponential) decay. For example, the medic… WebMay 22, 2015 · The relative uncertainty of the effective half-life propagates linearly to the dose. The biological half-life cannot be determined as precisely as the physical half-life, and the dominance of either rate differs from one radionuclide to another.
