Hello, I need opinions and pricing on instrumentation for the section of Ra226, Cs137, and Th232 ideally in as much as a foot of soil with concentrations as low as 1.7 pCi. I would like to use scintillation detectors hooked to an MCA and tow the array behind a vehicle but I do not have experience in procuring and pricing said instrumentation nor am I away of all the options available. So I would like to know if you are able to recommend instrumentation for those isotopes that can be used on streets, piping and buildings and if you recommend particular companies that make the instruments. I would require anyone who bids to have ample knowledge of these instruments and companies because I do not have the time or money to only get a bunch of webpages sent, I need lists and results.
