Need some Radon detectors

[laissez-faire]

Fairly urgently require an electric Radon Gas survey meter, able to detect radon in soil and water. Also need to detect some Geinium.

No budget constraints, can import from anywhere, just need a good reliable supplier. Any clues?

Thank you - I too had located that site but it is not electronic. I require a quantitative analysis.
