Hey guys.

I am currently working on a project for University, and would appreciate some guidance for it.

What we need to build is a radon detection. Our design is pretty simple - we’re building two Ionisation Chambers, on that detects alpha particles and one that doesn’t. How these chambers work is that they output a current signal that is proportional to the amount of radiation present in the air.

The idea is to collect the two current values from the two chambers, take the difference between them, calibrate them with some formula (found through trial and error) and get a value for the concentration of alpha-particles in the air in Bq/m3, and thus, the Radon level in the air.

What I need is some sort of interface or chip that can take in these analogue, current values, allow me to use them in some calculation that I programme into it, and then output the resulting number in a format that could be read and displayed on a simple LED display.

It doesn’t sound very complicated, but I am completely lost, coming from a Mech Eng background and not Electronics. I was recommended to use one of your products by the University’s robotic’s team.

Which product of yours do you believe is suitable for such a task? And how should I go about implementing it? I have a good background in programming, so I am not worried about that, but more about the electronics bit. What wires go where and that sort of stuff.

Any help is appreciated. Thanks
