1.0 INTRODUCTION

The following constitutes a supplement to the Annual Report for the Radiological Environmental Monitoring Program conducted at the Duane Arnold Energy Center, Palo, Iowa in 2015. Results of completed analyses are presented in the attached tables. For information regarding sampling locations, type and frequency of collection, and sample codes, please refer to Part I, Tables 5.3 -5.5 and Figures 5.1 and 5.2. All concentrations, except gross beta and airborne iodine, are decay corrected to the time of collection.

Airborne 1-131 is decayed to the midpoint of the collection period. The required values for lower limits of detection (LLD) for gamma emitting isotopes are established through the Offsite Dose Assessment Manual (ODAM). Naturally occurring radioisotopes, such as Be-7, K-40 and Ra daughters, are frequently detected, but may not be listed for every sample medium. iv 2.0 PROGRAM DEVIATIONS Sample Collection Date Type Analysis Location(s) or Period Comments SW H-3/ 1-131/ Gamma D-49 01-19-15 Water frozen.
