Crowdsourcing Radiation Monitoring In Japan

fysdt writes "A new open- and crowdsourced initiative to deploy more geiger counters all over Japan looks to be a go. Safecast, formerly RDTN.org, recently met and exceeded its $33,000 fund-raising goal on Kickstarter, which should help Safecast send between 100 and 600 geiger counters to the catastrophe-struck country. The data captured from the geiger counters will be fed into Safecast.org, which aggregates radiation readings from government, nonprofit, and other sources, as well as into Pachube, a global open-source network of sensors."

For the latter, use a well-defined sample volume and measurement geometry for reproducible readings.

      As for the diluted fallout from a reactor, that is very, very different from those scenarios. We are mostly talking about solid aerosol particles, in deposited form or drifting with the wind, which are very unevenly distributed, tend to accumulate in unexpected places, and generally stick to matter.

      So this is NOT
      - atmospheric monitoring. Radon or other well-distributed radioactive gases are a very minor factor
      - fixed and standardized geometry. The picture in the article shows somebody pointing a counter to the ground. This may or may not a location where the average concentration has been enhanced or diluted. And with gamma rays, the normal square distance law applies, so minimal distance variations have a large effect. For alpha and beta, the distance law has an even higher power, because the particles collide with air molecules, or water droplets in the air.
      - Cleanliness is a very major factor, and not just for the case of somebody sticking a counter into a puddle. If you just put a counter onto a mast, a radioactive aerosol particle may or may not deposit on the surface of the counter - and then stick. If it sticks, it will overpower any other radiation background, just because it is so much closer to the counter, and give much exaggerated readings. If nothing happens to fall on the counter, it will underestimate the dangers- if a radioactive alpha or beta particle is drifting by within just a few centimeters, hardly anything will register because of the very limited range of this type of radiation. Air-borne aerosol contamination can only be measured reliably by sucking large, measured amounts of air through a well-defined filter, and then measuring the radiation of the filter. Simple hand-held devices are completely useless for this purpose, even if they are dusted of weekly.
      - In any case, the most important task will likely be to identify hot spots *on the ground, or in water*, where major aerosol deposits have accumulated, probably aided by solution/evaporation processes, and then treat these, before they get airborne again.

      There was an interview with an expert in radiation leaks on BBC Radio 4 a couple of weeks ago that discussed citizens sourcing their own data. Even if you give them calibrated instruments you have to account for people positioning them incorrectly or not getting them re-calibrated every year or two. It helps if you are sending out known good instruments like this project does, unlike the current situation where we have lots of data coming in but no way to even guess at its accuracy. There have been lots of cheap and open-source Geiger counter projects lately but they are all pretty much useless.

      There is one other issue that rarely gets mentioned too. There are different types of radiation and depending on how a person comes into contact with them they can be more or less dangerous. Unless you have expensive equipment and know how to use it to measure soil, water, food and airborne levels of different types of radiation and different elements your data isn't going to be that useful anyway.

      As for the official figures they are published regularly and shown on Japanese TV news programmes. I suppose you could argue that they are fiddled but it seems unlikely since journalists and academics can get hold of expensive calibrated equipment to take their own readings. Actually I believe they said that some of the data is from universities, so the conspiracy would have to be massive. They have been quite open about the high levels found around the plant itself too. You can't hide radiation.

  10. Radiation detectors in cell phones by Keith+Henson · · Score: 1

    30 years ago I proposed putting radiation sensors in watches. When cell phones became common, I asked why cell phones don't incorporate them.

    I wonder if the current mess in Japan will bring cell phone radiation detectors to the market?

    Or if it has already?

    It would be pretty hard for the government to cover anything up, much less the freaking power company. This isn't a communist state you know. geez.

    That is sarcasm, right? I mean, yeah, it's not a communist country, but claiming that because of it the government and the power company cannot cover up stuff, or at least try, is pretty abysmally stupid. In particular because they are known to have done that quite a lot.
