APRS radiation monitoring

In the wake of the Japanese nuclear disaster there has been a surge of interest in interfacing Geiger counters to home weather stations so that radiation levels could be monitored via APRS. When you think about it, it seems a very good idea. Even if the measurements were not of lab grade accuracy, they would be good enough to show what was going on. It could avoid unnecessary panic – and equally make it impossible for officials to hide the existence of a radiation leak – if data from a network of amateur radiation monitoring stations worldwide was publicly available. This could be a real application to make APRS relevant even to the general public.

A standard for representing radiation measurements in APRS weather packets is being worked out as I write. The question is how to interface a radiation monitor to an APRS system and what hardware is needed to measure the radiation? Unfortunately, if not surprisingly, the final bid price of dosimeters on eBay has gone through the roof in the last couple of days. But in any case they all seem to be standalone instruments with no computer interface. I don’t know if a homebrew device would be possible, given that calibration would be needed, but if someone could develop one I think it would be a popular project.

    This project probably has the best chance of success and generating what you’re looking for:

    I think these are the same guys that put out the bounty for Open Source Kinect drivers, so the odds of them coming up with a solution are pretty good.

    As an amateur, I support this technology leap. This is a service I would love to explore. Please lets not let this just die off. This is a super opportunity to leap technology and public service.
    anyone have a working prototype? lets do this.

    Hi all,

    In 2016, I fail to understand why this issue still not interested hams :-((
    It is now possible to connect a sensor on the internet (for a reasonable cost: at least for a radio club equipment) and have a global vision using http://safecast.org/tilemap/

    But when internet is / will be down?

    Who knows examples of stations that broadcast such measures?

    thanks and 73

    RADLOG program offers APRS support for certain Geiger counters Mygeiger, NETIO and one other.
