Many substances are harmless at low dosages but lethal at a certain level. Aspirin is a good example. Low dosages taken every day are helpful to many people but higher dosages taken every day can be harmful and if you take enough at once it will kill you. The problem with the EPA’s models are that they will extrapolate down from a lethal dose and claim that a tiny dose is harmful in many cases even when there is ample data to show that their assumptions are not valid. The EPA is run by politically motivated bureaucrats not scientists. Even their bonafied “environmental scientists” are often politically motivated ideologues whose judgment is clouded by a hidden radical agenda.

A linear, no threshold model is what they use.

So 1200 people jumping off a one-foot drop causes as many fatalities as 12 people jumping off a 100 foot drop.
