Abstract
Details of a dynamic model of the global carbon cycle are presented, together with estimates of radiation dose to the world population from 14C produced by nuclear weapons testing (1945–1974) and 14C released according to a scenario for the nuclear power industry (1975–2020). To infinite time, an estimated population dose commitment is 540 man-rem per Ci released; this number assumes the eventual release of 3080 Gt (gigatons) of fossil CO2 and a population that is stationary at 12.2 billion after the year 2075. Sensitivity analyses show that within certain specified constraints, variation of dose predictions with environmental parameters is minimal, and that substantial future uptake of carbon by the biosphere would not diminish the estimates of population dose from 14C.
