Thank you for the check again. It was too dark yesterday, so i checked and took video of the same place today. My check is about 20 hours later, so the radiation probably changed, but I did not get the level as you did, (http://www.youtube.com/watch?v=rya-WpOsvLI ). I really don`t understand why, because it is exactly the same place, but maybe somebody can explain it to me...
I have read that the radiation level due to radon is affected by rain so maybe if it rained previous to your first reading that resulted in a different level.
