If I could afford the $130 I would buy one. I think you will remember the CIA and DHS say is is not a matter of [color:"red"]"if" [/color] it is a mater of [color:"red"]"when." [/color] I would like to be able to know the level of radiation and keep track of my total exposure. I'm not sure the directional feature is very important. A digital reading of total exposure would be a nice feature.
A long low exposure can be as bad as a short high exposure. It is the total radiation absorption that counts.
If there is a dirty bomb or a nuclear explosion you will be screaming for a bomb shelter and a radiation meter!
The sane adults of the 1950s are gone! Now we have left-over M.A.D. fools!
