This is the first opportunity that I’ve had to get a radiation reading on the ground, in the mountains. I had heard that the levels were elevated in places, such as Denver, where you’re quite a bit above sea level. For a comparison, let me show you the levels of radiation at various cities around the US.
Raleigh, NC – .11 uSv/hr
Tampa, FL – .10 uSv/hr
Dallas, TX – .07 uSv/hr
Los Angeles, CA – .13 uSV/hr
Phoenix, AZ – .11 uSv/hr
At 8500 feet above sea level, here in Aspen:
I would have guessed the level to be higher. So this is definitely a number I could live with if I were to spend my whole life up here (I wish!).
