Here is a picture of one of my basement unit, not currently online. Pictured is a Holmes HEPA air purifier with a GMC-200 connected to (not pictured) a Raspberry Pi running custom NETC software. The particles with radiation are trapped in the HEPA filter around the geiger counter. Sorry about the poor quality. I did a zoom first then used heavy compression to reduce the file size to save bandwidth on the forum.

@KingCobra, yes I agree. The filter is standard gauze. I'll add another layer or two so that air still passes through, but achieves what you describe. Thanks for checking it out. I already see a difference in the way the data graph is being rendered. I'll keep tinkering with your thoughts in mind. |

You could also buy the largest high quality furnace filter and cut it up to use as your filter material. |

Oh that's a great idea. I'll post when I've installed the furnace filter. |

I was washing some towels last night. As I was cleaning out the lint trap, I realized the thick half inch of clean white fiber would be a good temporary medium to trap all kinds of particles for monitoring. I tested the fiber with my Inspector EXP and didn't pick up anything beyond the background I usually get. I fashioned a new filter and positioned it right up to the tube in the GMC-320. Seems like I did it just in time as the equipment picked up a plume of something over the last 24 hours. In these situations, it would be nice to have a scintillator to get an idea of what's being detected. |

The new tweeks seemed to work. My station is now rendering a chart that seems to match what EPA stations are picking up on. And judging from those charts, it's a bad day to be an aerobic organism... I wonder if the Jetstream http://squall.sfsu.edu/gif/jetstream_norhem_00.gif has any role in today's hot airborne particles. Maybe the radon from Porter Ranch is a part of these measurements. I wonder... |

Here is a site that I find very useful for all types of atmospheric modeling. The bottom left corner has a menu that exposes a ton of options. This link should open it up at the Jetstream model. http://earth.nullschool.net/#current/wind/isobaric/250hPa/orthographic=-141.88,21.91,262 |
