"From current evidence, a judgement can be made of a threshold acute dose of about 0.5 Gy ( or 500 mSv ) for both cardiovascular disease and cerebrovascular disease.

Thus 100 mSv is considered twice in the table below once as received over a 5-year period, and once as an acute dose, received over a short period of time, with differing predicted effects.

However as early as 1972, investigators at the National Institute for Occupational Safety and Health ( NIOSH ) reported that a one-time acute dose of asbestos may be as harmful as the cumulative effect of lower doses over many years.

"The effect after several decades of a one-time acute dose ( of asbestos ) of limited duration . . . may be as harmful as the cumulative effect of lower daily doses of exposure over many years of work, " the agency's doctors reported in 1972.

And while the report's authors calculate that the odds of any single child getting an acute dose of pesticides are small, odds that a dangerous dose will reach a significant number across the whole population, 20 million U . S . children age 6 or younger, are great.
