Review on Radiascan 701A Dosimeter for Optimal Radiation Detection by Shawn Quick

This is amazing, especially for the price. It's far better than anything I've seen in this price range in both build quality and sensitivity/accuracy. In addition to being extremely durable, the device is configured in such a way that the GM tube really cannot be damaged. The only thing I noticed is the plastic cover on the part that should only block alpha and let beta/gamma through, but it's too thick and blocks a lot of soft beta. However, this is a minor nitpick and I will not be de-ranking anything as there are other ways to get the exact beta value by blocking the alpha.
