This GC seems very suitable for environment monitoring, and once I have tested out interfacing (which I found good descriptions of below) we will plan for placing 5-10 devices on top of water cisterns in the local community. We are located some 40 km from Ringhals nuclear power plant. This will provide an independent realtime information source. Again, a *very* nice device!! Regards, G
Re: Neighbor watch - kinoko 2014/07/30(Wed) 13:53 No.548 If you will build radioactive leak detector. it would be better to place the units around downspout. Soil on downspout acts as an natural accumulator of nuclear particles in rainfall. In 2011, many Japanese used to measure this spot to know radioactive contamination. and I guess it's difficult to measure correct strength of contamination on water cistern because water blocks radioactive emissions. thanksRe: Neighbor watch - Gullik Webjorn 2014/07/31(Thu) 00:14 No.550 Hello kinoko-san, Well, it is just because all water cisterns are located on high points and small mountains, so 1) we can link them with radio, 2) there is power, 3) they are exposed to wind. The prevalent wind direction is from south-west -> nort east and that follows the "viskan valley", where all the towns and villages are located. So if something happens at Ringhals, we have between 1-2 hours before our homes are contaminated, with a 5m/s wind speed.
Thanks for the tip of downspout, that will be fine for long term leakage. Regards, GRe: Neighbor watch - kinoko 2014/08/04(Mon) 18:27 No.551 hello Gullik Then that's an ideal place. however if the electric power on the place is coming from Ringhals nuclear power plant. you should add auxiliary power source like UPS unit or solar power unit with batteries. The system should be fault tolerant.
