Live Radiation Data from Newquay Weather Station


2011 - I searched the net and this may be the UK's first public geiger counter data available in the UK.
8/10/2018 Check out the new Geiger counter Netio GC10

Data from Newquay, Cornwall. UK - Operational from 24th May 2011

Latest data 21 uR/hr at 16:40 21/12/2024

NOTE : The 24 hour graph - Resets when PC rebooted

Last reboot 12 Days 0 Hours 11 Minutes 42 Seconds ago

Select a monthly radiation graph and click submit:
Last 24 hr graph updated every 5 mins, month graph every min. 29th May 2011 - 24 Hr data reset, new beta software, uploading to blakcatsystems world radiation map and european map here now so graph data in uR/hr to match other sites.

The data provide here should be considered as an indication only.

The geiger counter is a GM-10 (serial version )
The GM-10 contains a geiger mueller tube, capable of detecting alpha, beta, and gamma / x-ray radiation. Each time a radiation particle enters the sensing window, it is detected and the software on the weather PC adds up the number of detections and the Counts Per Minute (CPM) is calculated. The software creates a CPM graph which is uploaded at 5 min intervals to the webserver.

Today radiation is everywhere, it is known as background radiation ( more information Here ) and can come from man-made ( fallout from nuclear testing in the 1950's and 1960's) and natural (such as radon, cosmic rays), there is always some background radiation present, which can fluctuate due to weather evens such as air pressure, rain or even dust.

 gm10
Location The geiger counter is temporarily positioned in front of a double glazed patio door, pointing north, whilst I find a suitable enclosure for mounting external such as a webcam housing.

More information on the GM-10 can be found here www.blackcatsystems.com
