Collective effective dose

The quantity collective effective dose (S) of a group of exposed persons i = 1, 2, ... who each receive an effective dose E_i is defined as:

S = ∑ E_i

The corresponding unity is manSievert (manSv).

By tracking the collective effective dose of the group through a number of years, one gets an impression of the development of radiation protection practices. However, if the individual dose for the 10 billion people on this planet each increases by 1 nSv, the product 10 manSv is not meaningful.
