The radmon.org radbox-20

Great news
My settings are 0.025 detect level and 0.5ms for minimum pulse width and dead time. These are probably different from the defaults in v0.41, I have changed them since making the radbox-20. These will be the new defaults in v0.42.
I'm very glad you like the build quality and component choice. I used better quality parts, connectors, cable and enclosure. This has increased the price somewhat, but IMO are essential for use outdoors, proper watertightness, decent low noise cable etc.

I've attached a screenshot of my settings for the RadBox-20.

Just to repeat what's already been said in that this is a very well put together piece of kit using good quality components, so have no fear of using it outside. This is where it's designed to be, monitoring the environment.

Mine has been operating for just over a week sans problems and I'm very happy with its performance.

Ok some of you who keep a regular check on stations on radmon.org might have notice my station information change to 'Testing radmon.org radbox-20' or something along those lines.

That's because I have been making an external, waterproof background radiation monitoring box that will be available to buy on radmon.org........ and there will be a cheaper DIY version and also a high sensitivity SBM-19 version, called the radbox-19.

Dan, I would be very interested in your thoughts about planning the production of the Radbox-19 as I think the extra order of magnitude in sensitivity would be very useful in detecting natural radiation fluctuations, such as radon washout and radon "burps" from the ground. I know the Radbox-19 won't be able to detect radon directly, but it would be able to detect the beta and gamma emitting daughter radionuclides. Likewise, it could possibly detect Forbush Decreases following CME impacts, even lightning produced gamma flashes - who knows??

Last night I noted another dip in the cpm for a few hours, not as big as the one last week, but a noticeable dip nonetheless.

There was another dip last night. Again around the same time, beginning late pm and then ending in the middle of the night. This is the third time it's happened since the Radbox-20 was installed. Maybe something, maybe nothing.......
