Will this accurately measure Cesium 137 and Plutonium radiating from canned fish?

I'm not sure the unit is sensitive enough to detect the minute emanation from possibly contaminated food. Back in the day, Amazon sold a radioactive sample for calibration purposes (I haven't seen it around for awhile, though) and the unit did a pretty accurate (just a few marks off) reading of the sample. You may need a more sensitive (and expensive) unit for the food reading...

Hi D.A. I have one (purchased through Amazon) and the 1503 is a fine little pocket Geiger counter. Be sure to read the manual and understand its operation --cumulative 160 second timed averaging in particular. In answer: while food that's 100 or 1000 times more radioactive than the "safe to eat" limit^ might be noticed when scanned with the RD-1503, no Geiger counter can read food or beverage as being safe, nor can specific isotopes be identified for sure. That takes training, discipline, seasoned experience and thousands of dollars worth of gamma spectrometry equipment. The FDA and your state health department should be doing this work --but they seem to not want to know --or want us to know. ^ Interestingly, Japan's limit for radioactivity in seafood is 100 Bq/kilogram, while ours and Canada's is 1200 Bq/kilogram. It would be a crying shame if our fishing industry got put out of business simply for lack of testing and/or consumer confidence.

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.

It goes from 0 - 999 microsieverts. The radiation I took pegged the machine out at the 999. From how I used the machine, it seemed pretty accurate. And yes, it will bounce around at the low end as .18 microsieverts is pretty low to begin with. Love the machine and will use it again if I am in need of another Radioactive Iodine treatment. I feel comfortable knowing that the readings in the house are now normal.

The kind of material that the container is made of has nothing to do with it. This hydrometer works by displacement so you must make sure your container is tall enough to work for high and low proofs. I think you're wanting a 'thermometer' reading but the fishing bobber is exactly how it works. YouTube someone that can help you understand it if I didn't help.

Yes! In fact, this is one of the most widely used brands of personal Geifer Counters in Japan today. These Geiger Counters have been tested and reviewed by the Japanese Consumer Protection Agency, with determined accuracy identical to that of a $2000 lab station the size of a typewriter! We are proud to say that as far as calibration and accuracy is concerned for these purposes, RADEX Geiger Counters are second to none. Please see pictures of our Geiger Counters being used in Japan. Please note elevated readings (normal is lower than 0.30 uSv/h) http://www.quartarad.com/images/M_images/fukusima-house.jpg http://www.quartarad.com/images/M_images/fukusima-street.jpg PDF: Japanese Consumer Protection Report on testing different Geiger Counters (In Japanese, but there are pictures and comparison charts). http://www.quartarad.com/images/product/consumer-protection-japan.pdf

I would not even consider trusting it for that purpose. I'm sure there are more job specific tools to measure the amount of radiation emitted by an x-ray machine. In a situation of an extreme emergency or disaster I might put it to the "Test". But otherwise I would not attempt it.

The detector will show you the cumulative dose and you will be able to see how much radiation was absorbed during the specific time period. In order to measure the dose a radiation dosimeter has to be present. However, if an object absorbed a significant amount of radiation and became "radioactive", meaning the radiation is coming from the object, the SOEKS detector will be able to pick it up simply by getting the detector close enough to the object you'd like to measure. The other option is to measure a radiation background away and near the object, subtract two numbers - the difference is how much radiation the object emits.

It will not test the salinity. It test the amonia, pH, nitrite and nitrate levels. What your looking for is a refractometer

Yes, it measures to three decimal places, however, there is a +/- in accuracy, but it meets DOT requirements (also meets Nuclear Regulatory Commission Part 26 Fitness for Duty requirements).

I don't think so. For one thing the radiation administered is very low & short acting, second, the Radex is designed to detect gamma & beta radiation as per the manual that should have come with your unit.It will measure in both micro sieverts/h or sv/h & micro rems/Rem/h of radiation. While the dose is high enough to affect the cancer into which it's injected, it's not high enough to affect adjacent normal cells as it only penetrates about 11 mm.

Jeremy, tens of thousands of these units were sold in Japan and are continued to be sold today. So, yes, it can be used to detect radiation in Japan.

I'm not an expert, but I believe this could detect certain kinds of radiation in food, but not others. So there's no guarantee that the food is safe just because this didn't detect anything. I think food has to be sent to a lab for the more proper testing. Still, I went ahead and tested a lot of food and didn't find any problems.

I've read claims it can, but not 100%. I'd use an ion-exchange filter also. Is your water in a high radium area (such as Radium Springs near LaGrande, OR)? You might want to look into a dosimeter/Geiger counter to check after purification. If you're worried about Fukushima, you wouldn't be looking for radium but other isotopes, most of which are not gamma emitters (and wouldn't be detected by Geiger counter)>

Fill the drop spoon with exactly the stuff you want to measure, then weigh the amount. That's the most reliable way to find out.

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'.
