What types of radiation are measured? Alpha? Beta? Gamma?
276028
Thank you for your question. The device is able to detect ionizing radiation and store the readings up to 3 years for Beta, Gamma and X-Ray Radiation. If there is an Alpha radiation source in the object there will be Beta or Gamma decoys which the device will successfully detect. The radiation coming from the Fukushima is Beta and Gamma.

The GMC-300 is easy to use and low priced as an entry level radiation detector. I use mine to monitor background levels of radiation as I have yet to find an highly active source. Here in central BC, Canada I get 14 to 22 cpm, with a high of 30 cpm. It appears to decrease after a rain fall. The only thing missing with the GMC-300 is a radiation standard but I can understand why.

I am assuming you are referring to chemical radiation like fallout since you said "also" It is very finicky and can get inaccurate reads by interference or random amplification and canceling behaviors among the various waves present in its location, but it does give an indication of the strength of wave activity in comparison to other nearby areas. An accurate instrument is much too sophisticated for a lay person to have as a consumer level product. I think they make instruments that detect the presence of chemical radiation, but this just claims to "detect" the presence of EMFs and provide a somewhat general level reading from room to room.

Alpha and beta yes, in combination with respiratory protection. Not gamma, X-ray, neutron.

No it is not a spectrophotometer . It is a crudely simple radiation counter. It is mainly gamma rays sensitive. The most interesting usage I had from it was from taking it up in a commercial jet on a holiday and watching the radiation levels soar to about 20 times what it was in my kitchen. (This is well-known but still interesting to see oneself.) I have also detected beaches that were radioactive with natural thorium but it has to be laid on the sand to work. It's a bit crude and it is worth knowing the basics of radiation counting before you use it, for example what a sievert and or micro-sievert is.

You can not measure radioactive contamination in food or liquids with any geiger counter. THERE IS NO WAY! To measure food or liquid contamination you will need a lead shielded chamber, a scintillation detector and you have to completely dehydrate and grind the samples. Beyond that you need sound knowledge how to calculate proper values.If a geiger counter starts nervous clicking on your food or drink something went badly wrong and the question wouldn't be 'can I drink that'. It would be, 'How the hell can I get out of here'.

I calibrated mine using a iOne calibration tool, granted it wasn't off by much but i needed to calibrate based on a different gamma value than the 2.2

I don't think so. I'm pretty sure you need a different type of radiation detector. Look into an electromagnetic radiation detector.

The Radiation Detector "Soeks" is designed for assessing the radioactivity level of any item and detecting objects, food items and construction materials contaminated with radioactive elements. It easily gauges radioactivity levels based on ion radiation intensity (gamma radiation and beta particle stream) and x-ray radiation levels. - See more at: http://www.soeks-usa.com/product/radiation-detector-soeks-01m/#sthash.mkSH30NF.dpuf

No, It only used to measure electro magnetic radiation in radio frequency range such as radiation from microwave tower, Wi-Fi, Microwave oven, wireless communication etc.If you want to measure EMF for AC unit motors & other home motors, you need a meter which can measure EMF in power frequency such as Trifield 100XE meter. Thanks

Yes, the device has Japanese, Russian and English displays. The device measures background radiation, i'm not sure of its effectiveness in liquids, but if it is significant it should detect.

Since x-rays are a form of ionizing radiation, I'd say yes. That's what it's supposed to detect.

With all devices you get what you pay for.. This one is pretty cheap and there are a lot variables that come into play. I would not buy the same one knowing what I know now. You will need to do more research on what type of radiation you are looking for. For instance do you want to detect or determine a dose absorbed?

I recommend the Trifield 100XE EMF Meter for those sort of readings. It's cheaper, accurate, and easy to use. The extech is best if you want to measure radiation from cell towers etc.

No. Geiger Counters detect Gamma, Beta and X-Ray radiation. Radon Gas is Alpha particles and you need a special device to detect those properly. RADEX brand carries an easy-to use, highly practical Radon Gas detector: MR106N. Please see our listing here for more details:SIRAD MR-106N Radon Detector (Eng)Best Regards,Dmitry C.Quarta-Rad, Inc.

Hello, Brent V. With cellphones or wifi the potentially harmful radiation is radiofrequency (mostly in the vicinity of "microwave oven" radiation, around 2.4 Ghz) because these frequencies are particularly prone to do eventual damage to us. If I correctly recall, there are devices for measuring "rogue microwaves" but they are mostly to detect badly sealed microwave ovens.

I haven't used mine yet but as I understand most all metals. It has different settings for what particular metal you are wanting to detect.
