WebIn one half-life (one minute in your example), each and every atom has a 50% chance of decaying. Now think of the atoms as dice. Each minute you throw the dice, and those that roll three or less you remove - they "decay". That means each dice has a 50% chance of being removed each minute. Thus, your dice have a half-life of one minute. WebMay 19, 2024 · When a drug has a short half-life, that means the effects of the drug will arrive quickly. It also means the drug and the effects will leave your system quickly. Medicines with a short half-life must be taken multiple times throughout a day to feel the effects consistently. Substances with a long half-life will take longer for effects to appear.
