15. The role of total dose in radiation effect
If we compare guzzling a bottle of wine in one go to sipping on it for a year, it is unquestionable that the former would be more dangerous to our health.
This goes the same for radiation effect as well.
In the case of being exposed to "the same total dose of radiation," longer exposure time has less effect to our body than shorter exposure time, although it sounds awful to be exposed for an extended period of time.
It is important to note that this only applies under the condition of consuming "the same total amount" of alcohol. Spending 10 days to drink a bottle of alcoholic beverage has the less physical burden on our body than spending 1 day.
