The device can should do everything of home users. It is not a scientific instrument but has nevertheless some features and options, esp. Long-term recordings. Think it is well suited for the radiation indication. The selectivity for alpha, beta or gamma I can not judge, but I suspect that the setting is only effective if the exact points to a concentrated source, not in background radiation. Basically, that's less interesting for domestic use. In any case, the manufacturer's support does not answer the question in this regard, Furthermore, there are deductions for the poorly designed cover to the USB port, and last I bemängle that the device did not work out the first delivery properly and had to be replaced. That was the real reason of the request from the manufacturer because I suspected a defect, but also on this question I received no response. I therefore canceled the unit and ordered a new and behold my suspicions were later confirmed. An innocent purchaser runs forever with a defective unit and is pleased with depth (but incorrect) measurements.
Nevertheless, I am glad to have bought this device, it is compact and lightweight. Old military equipment is too bulky, other providers of newer devices are too expensive and some are too simple, eg also the Gamma Easy. The alarm function and the battery version make it in my view, only more expensive and the alarm device, it will only unnecessarily wasted battery.
