Dear Hansman. I appreciate your answer. My University wishes to purchase the equipment possibly if it can get a used version at a much reduced price. I'll also appreciate if you also have any information regarding that. However, I will send a mail to the company to inquire if there's any special package for University. Many thanks.

a cheap way to measure radon is to use scintillation flasks and a photomultiplier. A company providing this kind of equipment is Algade (which produces the photomultiplier CALEN).

Otherwise, I know that some people use BARASOL (http://www.algade.com/index.php/english/Mesure-en-continu-du-radon/mesure-continue-radon-sol.html) to measure radon in the ground. Check whether it can measure radon in water, I don't know.

Good luck

Maybe you can check previous works from Paola Tuccimei, it could give you ideas

Radon Monitoring with AlphaGUARD is fine for atmosphere, gas and in water (with some modifications) and find detailed inf at http://www.genitron.de/products/products.html. However, radon bubbler will help lot.
