 - On a second thought, the "finger electrodes" may not be a good idea. Since there is a large contact area between each finger, there surely is a lot of leakage current that will mask-out any ion-induced current (one of the biggest concerns explained by [Charles Wenzel's ion chamber website](http://www.techlib.com/science/ion.html))
 
-- 19/Jan/2017 Finally got a .9uCi AM241 source to test, it will be the benchmark for the detector. Unfortunately, the first attempts with the amplifier circuit yield very noisy measurements, that mainly depend on wind and humidity. Surprisingly, it is also very dependent on static electricity. I've also tested again the spark particle detector, but there seems to be absolutely no relation between the sparks and the proximity of the radiation source. ¿Maybe the finger electrodes are too "pointy" because of the manufacture method (milling)?
