POSTMAX can be part of a two-step process to determine the 95th percentile MEOI χ/Q for a facility and accident. In the first step, MACCS2 is used to determine the dispersion values (χ/Q) according to the facility parameters and the hourly meteorological data. The models and instructions for MACCS2 are provided in NUREG/CR-4691 and NUREG/CR-6613. MACCS2 generates a table of χ/Q according to distance for each hour evaluated. POSTMAX reads the MACCS2 output, meteorological data, and site boundary distances to calculate the Maximally-Exposed Offsite Individual (MEOI) χ/Q for each hour evaluated. The MEOI χ/Q values are sorted to generate the cumulative distribution function (CDF) and the 95th percentile value is identified.
