Radiation just spiked to over 5000 cpm in Ireland! | |
Anonymous Coward User ID: 31189518 United States 08/06/2020 03:50 AM Report Abusive Post Report Copyright Violation | 5000 cpm of what? Quoting: Anonymous Coward 78893046 Alpha, beta, x-ray, gamma or neutrons? What's the baseline calibration? Cpm numbers are meaningless unless the detector and radiation type match and there is a known calibration standard. Entirely irrelevant when either are a problem CPM are useful when compared over time. The relative difference is what's important. If a detector is running background counts, then spikes and slowly reverts to the mean, you can infer that it's probably a radiation event rather than a broken detector. If you have two that track in magnitude and direction, then you can be reasonably sure it's a radiation event rather than a detector malfunction. Absolute calibration increases the utility of a device but is not necessary for it to be useful. In all likelihood, the device was a gamma detector, probably a standard geiger counter. |
Anonymous Coward User ID: 31189518 United States 08/06/2020 03:58 AM Report Abusive Post Report Copyright Violation | Beirut officials are claiming that the 2,700 tonnes of Ammonium Nitrate has been stored there since 2014. Quoting: GSB/LTD I just checked and UNOPENED, Ammonium Nitrate only has a shelf life of FIVE YEARS. If open and exposed to the atmosphere that time is reduced to only ONE YEAR. It also does not become unstable as it nears expiration... instead, it loses volatility. You have a very good point. And to be stored in a waterfront warehouse too... Any number of tons of ammonium nitrate or any other oxidizer CANNOT explode without a molar equivalent of fuel, regardless of its age! There was no mention of any fuel that could come into intimate contact with the oxidizer, so that story is bullshit. There needs to be an explanation that fits the facts! |
Anonymous Coward User ID: 68733398 United Kingdom 08/06/2020 05:53 AM Report Abusive Post Report Copyright Violation | Hey all, admin of radmon.org here. It's a network of private geiger counters, a large proportion are home made, DIY type counters. Some are indoors, some are outdoor, there are several different types of detector tube. There are varying quality of builds and reliability of these detectors. Some are online 100% of the time rock solid stable. Others suffer intermittent problems. Imagine trying to maintain calibration across such a wide variety of detectors for accurate reporting in uSv/hr. You would need to dictate the equipment standard and test. DIY builders generally don't have access to known check sources. It is a private network of enthusiast built counters, with zero funding, apart from the interest and dedication of the builders themselves. No government funding, nothing. So, legwork and understanding of what is reported is expected. For example, the type of tube and other details are recorded in the station description. The station's history is recorded, so relative readings can be compared. Results are UNFILTERED, just like you like your news. No one can dictate changes to data, apart from me of course and I'm a stubborn old mule with regards to radmon.org's independence. With unfiltered data, you must be able to understand there may be station malfunction and other problems to exclude before coming to the conclusion of an actual radiological event. People who claim the data is useless irk me, because as a poster said a few posts up, the data is still very useful and you can make relative conclusions from it. In a dangerous situation would you ignore your geiger counter readings because it was not recently calibrated against a check source? Of course not. Just some effort thinking about what radmon.org is and real life practicalities, will lead you to the reasons why. Also threads pointing out alerts here are still useful as more eyes and heads can analyse the data to see if it is worthwhile. Most of the time the alert can be discounted. But sometimes, like the coronavirus in January, shit can get real. Love GLP by the way. |

Not Ireland. haha I think maybe OP mixed up his geography. How do we request a title change to get it changed to say Italy? More people should see this thread given it's location across the sea from Lebanon. I wasn't confused. Ireland did have a spike. I knew about italy. |

User ID: 75937200 United States 08/09/2020 03:12 AM Report Abusive Post Report Copyright Violation | Yes. Florida keeps going back and forth between dark red and green. Ireland, what OP originally posted, has been yellow since I started watching the map. I don't know what Ireland was when he initially posted. But Sicily, has remained consistently bright red "alert" at 447. Can't help but recognize it is directly across the mediterranean sea from Lebanon Which way do the Med winds blow? The radiation escapes into higher altitude and there it moves from East to West. LIKE IT DID WHEN TSCHERNOBYL FUCKEN RADIATION WENT ACROSS WESTERN EUROPE! All enemies, foreign and domestic. |
