A Comparison of Alternative Methods for the Calculation of Dose to
the Maxmally Exposed Individual and Population Surrounding the INL
The Environmental Surveillance, Education and Research (ESER) Program
has undertaken the reevaluation of older procedures and methods for the
calculation of both dose to the maximally exposed individual (MEI) and
population dose. This comparison evaluates the methods for obtaining the
MEI and population dose using computer programs developed previously
(many in the early 1970s); with obtaining the same values using current
technologies, to determine equivalence.
Every the year the ESER Program prepares and issues the
Annual Site Environmental Report (ASER)
for the Idaho National Laboratory (INL).
A key portion of the ASER is the reporting of the dose to the MEI and to
the population within a 50-mile (80-km) radius of any site facility. In
the past these dose values were obtained through manual calculations and
FORTRAN computer codes. The limitations of FORTRAN lead to necessary
assumptions being made in the calculations for the program to run. The
following discussion is to detail that an alternative method, using more
powerful computer programs unavailable at the time the original codes
were written, will provide a more accurate and much simpler process to
obtain the MEI dose and 50-mile radius population dose.
