1.0 INTRODUCTION

The following constitutes Part II of the final report for the 2020 Radiological Monitoring Program conducted at the Kewaunee Power Station (KPS), Kewaunee, Wisconsin.

Included are tabulations of data for all samples collected in 2020 along with graphs of data trends. A summary and interpretation of the data presented here are published in Part I of the 2020 Annual Report on the Radiological Monitoring Program for the Kewaunee Power Station.

e 2.0 GRAPHS OF DATA TRENDS

- Note: Conventions used in trending data .

The following conventions should be used in the interpretation of the graphs of data trends:

- 1. Both solid and open data points may be used in the graphs. A solid point indicates an activity, an open point, a lower limit of detection (LLD) value .

2. Data points are connected by a solid line. A break in the plot indicates missing data .
