Admittedly not want to really need you on this product. But I live just off the Czech / Austrian border about 30 km from Dukovany (nuclear power plant). As I am sure that we are not warned in time if a fault occurs, I will now automatically perform measurements to increased radiation values to detect at least once and possibly take protective measures can. As I said, no hysteria but respectful caution. For device: At first I was on the fact that there is still a very simple device is very surprised and not very enthusiastically. The very fact that you have to calculate from a click rate only a microsieverts burden me befremdetet first. After sufficient information about your family from the I-Net I quickly realized that one needs to know only about the increased radiation exposure in the event of the case. Everything else does not count anyway. So all up about 1.6 clicks per hour is anyway completely safe about it one should even put his own warning limits cope and have prepared a corresponding thereto emergency plan. Do not forget the device, then it is supposed to show again whether you have visited a less polluted place. I know it's all just theory, and perhaps a little wishful thinking mixed with heroism. No matter. Anyone with whom you can regularly check an increased radiation compatible device search will be well served with this. To comparatively little money, there is a good (I hope also robust [it looks it]) meter. I can really recommend it, at least, since the device (which is already a rarity) in the European space, is a German company that built and sold. Lo and behold, the thing also does not apply after "China plastic" to. Toll - 5 Stars
