2. Doses Due to Gaseous Effluents The 50 mile Ingestion Zone population is 1.47 E+06 persons.

The Maximum Real Individual is located at 2896 meters (-1.8 miles) in the ENE sector The Maximum Hypothetical Individual is located on the site boundary at 2140 meters in the SSM sector.

D. For the Inside Site Bounda ry Individual, access time is assumed to be 400 hour0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br />s/yr at 1207 meters (3/4 mile) in Concurrent meteorology is applied separately to hatch and continuous release source terms.
