Carried everywhere your keys go, NukAlert's 24/7 constant radiation monitoring, alerts you if you are being exposed to dangerous levels of radiation. the NukAlert is a compact key chain attachable radiation Monitor & alarm. Monitoring is always on, using a built in long-life (ten+ year) battery. The devices range encompasses higher emergency radiation levels. There are 10 easily recognizable 'chirping' alarms. The NukAlert has a Patent-Pending 'State of the Art' Detector Technology that has been verified by independent National Radiological Laboratory. Each NukAlert is individually tested for radiation detection accuracy. Package includes an instruction manual with personal nuclear survival strategies. It Meets the FCC and European Community requirements for Electromagnetic Compatibility, emissions and susceptibility. it has also, passed EMP immunity tests and meets the MIL-STD-461D, RS105 standard. its has a 2 year warranty plus a 10 year prorated warranty. NukAlert is made in U.S.A.

The number of chirps gradually decreased until stopping after more than 1 hour. Since the xray dose was momentary I had expected it to stop much sooner. In a real radiation situation I think its constant chirping could give a false impression that you're still surrounded by radiation even if you might have vacated the source area.
Another problem is that it measures radiation in Roentgen units, which I later learned is a legacy unit of energy. The problem with this is that because most reports of radiation I hear or read about is in Sieverts, I'm now learning that I must convert from Roentgen to Rad, which is the dose equivalent, then from Rad to Gray, which is the SI equivalent, then from Gray to Sieverts. What further complicates this is that because some of these scales are affected by dry air versus soft tissue, there is no standard method of conversion. Basically I want to know what n mSv = n R, and that x number of chirps = n mSv so that I understand what's going on in my environment & share information that is meaningful to others.
When comparing this to the K8, I chose NukAlert because it reports detection of DANGEROUS LEVELS of radiation whereas the K8 detects only very low levels. The table on the back of the device helps determine what the exact situation is.
This is a Dose meter to alert for dangerous doses of radiation. It is not a toy, it will not detect low levels of radiation that are not "acutely" dangerous. If you don't know the difference between a Dosimeter and a Ratemeter don't buy ANYBODYS "radiation detector" until you do, as you might just waste your money.
While it does start alerting at a low level, it is not really to be used as a Ratemeter to detect the currently low levels of radiation from Japan or check on the radioactivity of Vaseline Glass or Fiesta Ware plates.
If this sounds it's alert, it means there is a serious issue brewing! The reason I bought mine is for protection (notification) against dangerous levels of radiation from Radiological Dispersal Devices (Dirty Bombs) and a gross indication of Nuke Weapon radioactive fallout levels.
I have a Ludlum Ratemeter that will detect low levels of radiation, the NukAlert is a companion to use when the ratemeter is no longer the appropriate instrument.
This is approved for purchase by Agencies of the US Government and Military, which is why the description includes all those facts, specifications and MSN numbers that apparently confuse some.
It's too bad that one seriously misguided and jaded individual without purchasing the item decides to rate this at one star because they don't understand technical lingo. To write a negative review and give a severely critical rating of a product you've never used, because YOUR confused is malicious, mean, seriously screwed.
