What is the best device for detecting current dangerous radiation?Say the stuff in the Fukushima Reactor?

Radiation detectors only pickup decaying particles close by. You would need to be close to Fukushima area to detect anything serious. Unless you're going to Japan I would suggest something reliable and inexpensive like the www.amazon.com/International-Medcom-CRM-100-Digital-Radiation/dp/B006C4ZTEK .

This detector will work through anything. The unit picks up elector-magnetic field that all metals give off and these EMF penetrates everything.

Cylindrical low voltage SBM20-1 tube. Only does Beta and Gamma. Its does work well. A nuclear plant recently had a leak about 245 miles north of me, and it went bats as I was downwind and it showed elevated radiation at 6 times my normal background for 45 seconds so I know I caught a wisp of it. This is not professional lab equipment, but is good value for what I paid for it. The battery life is awesome too with LSD rechargeable NiMH AAA batteries. I run it 24/7. At this price, I do not really care about tube life. Just do not expect professional grade results from it, but it is good enough and a good value for the money.

Holly, this is a field technicians, consumer grade, instrument designed to detect radiation. By design, it measures a very small percentage of the radioactive particles emitted by a test material. To get a precise measurement of the total radiation given off by a material the material would have to be sent to a lab and tested under controlled conditions. This said, my Radex detector has been the only means I have of removing radioactive liquids and foods from my diet. Last year, before I realized my food supply was contaminated with radiation, I was in constant pain and my feet were so swollen I couldn't get my shoes on. My Thyroid gland almost shut down I my doctors just gave me pain medication without trying to find the cause of my medical problems. I had purchased my Radex detector, I believe, in 2011 but never used it. Frustrated by not getting answers from my doctors I started looking for the cause of my medical problems myself. Within 24 hours after removing all the contaminated food stuffs from my home the swelling in my feet for the first time in months went down to the point I could put my shoes on again. In three weeks my Thyroid gland started to function again. It's been almost six months now and I am still pain free. I have made checking my food supply with my Radex a routine.

Itr is easy to use. Yes for something like that a great tool. Detects a few inches below earth. For the price u can't go wrong.

This unit does not give out radiation. That is not something that any one can sell over the counter. Radiation is harmful and has to be regulated.

There are four types of radiation...Alpha, Beta, Gamma, and X-Ray. The only radiation the detector is guaranteed to detect 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.

i can only answer the last question. buy an expensive radiation detector. i don't recommend the radex rd1503!

It will detect the radiation emitted by radon gas, but it is not, per se, a radon gas detector. There are detectors sold which are used for a few hours up to a few weeks that you set out, then send in to get a radon level count. I'm sure those would prove far more useful if that is your goal.

Unfortunately, this device only detects STATIC lightning discharge. If you are in an area where Tornadoes are prevalent, you may do well with purchasing a weather-radio with severe weather warning capability (S.A.M.E.)http://www.nws.noaa.gov/nwr/info/usingsame.html

go to Kellyco metal detectors , this is one awesome machine I have found targets at 3 feet with this guy in all metal mode !!!

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!

Not sure, I'm a beginner with experience with a cheaper brand. After using this model I must admit my old metal detector "toraso cultus" is much easier to use and detects just as deep. I'm not certain the price gives me that much more of a detector. I'm still learning it but am becoming a little frustrated.

No. The device doesn't detect Alpha radiation. Alpha has very short waves and can not penetrate skin or thin layer of air. However, if there is Alpha radiation there would be Beta or Gamma one as well. It's almost impossible in a real life to find Alpha radiation alone. intelGadgets.com

Wish I could help as I am all about these detectors, but I would reach out to the manufacturer via their website for that information. Sorry.
