Thank you for your help. Will recommend this page to anybody with these questions - not many around me at the moment, but - unfortunately - I'm sure there will be many, very soon. :(<br><br>bonoreply@blogger.comtag:blogger.com,1999:blog-5633785047528618668.post-43780680680869288012014-03-28T23:36:10.760-10:002014-03-28T23:36:10.760-10:00Thank you so much stock!

So the way you measure bequerels would be :<br><br>1.Set your geiger to counts per second ( CPS)<br>2.Measure the weight of food item ( how many kg)<br>3. Divide CPS by kg ?<br><br>Or is that an over simplification ?<br><br>The school ground dirt in my hometown in Japan measured 75bq/kg last august for cesium.<br>I'm still trying to understand what that means.<br><br>bonoreply@blogger.comtag:blogger.com,1999:blog-5633785047528618668.post-40118392960896136812014-03-27T13:20:18.164-10:002014-03-27T13:20:18.164-10:00Watch the second video, you will then understand W...Watch the second video, you will then understand What a CPM is in relation to a Bq. Simply when a decay hit a Geiger Mueller tube or pancake, it creates a "click".<br>But Geigers are different shape and sizes and have varying ability to detect radiation (thats called efficiency). A bigger pancake type will "catch" more clicks than a smaller tube.<br><br>Also some are just better quality...they will catch more, even of lower energy decays. Now watch the video of the food sample ...you can see how your geiger would only be catching a portion of the radiation. And some 50% that hits your geiger wouldn't even cause a click. <br><br>Stockhttp://www.blogger.com/profile/04516118374677265589noreply@blogger.comtag:blogger.com,1999:blog-5633785047528618668.post-47662057066130433672014-03-27T12:32:18.211-10:002014-03-27T12:32:18.211-10:00Thanks for this great video.Great walk through com...Thanks for this great video.<br>Great walk through comparison of inspectors geigers and scintillators.<br><br>And finally some eureka on bequerels, that is the hardest one to grasp for me.<br><br>40 bq/kg - that means 40 atoms decaying per second. Hard to visualize that, but is there any chart that connects bequerels to either CPMs or sieverts?bonoreply@blogger.com
