Radioactivity measurement - First hike of the year

Measurement done during the first hike of the year in the Flatside Wilderness area (AR).

Radioactivity measurements - introduction

Just for fun I started to collect some radioactivity measurements.
I did something similar 35 years ago in Italy with a DIY kit from Nuova Elettronica.
Why ? Well, as I said, just for fun and curiosity and don't forget we have a nuclear plant in Arkansas. Never hurt to monitor if something fishing is going on (and no, so far everything is fine for what I can say :) )
