Re: Radon Kits
Sun Nuclear is a good way to go and an affordable way to get started. I have their new Model 1029 and I like it. People like the hourly readings and the pretty little graph that you get with a CRM. And the tamper-detection features are a plus. But you can only do one radon test at a time with one CRM.
I would recommend that you consider an E-PERM system from Rad Elec. It costs more to get started than other systems but the cost per test (after purchase) is very low and E-PERMs give very accurate results. With a few pairs of E-PERM chambers you can do several radon tests at once. (You hate to tell a client you can't do their radon test because your only device is already in use on another test.) E-PERMs are fully-integrating devices (unlike charcoal devices) and provide almost immediate results but only give an overall average (versus hourly readings with a CRM) and do not have buillt-in tamper detection. E-PERMs are VERY versatile. They can be used for short-term and long-term radon testing. They can be used to do radon-in-water testing. With an ERPISU device they can be used for radon decay products testing. Every now and then you can find some pretty good deals on used E-PERM systems on eBay.

Re: Radon Kits
We use Radstar 300s' AccuStar Labs
Easy setup, hourly readings and average measurement, tamper indicators. Plugs in to your laptop to produce the report. Pay one price, that's it...except for the $145 yearly certification.
I've got 5 of them here in MN and haven't had an issue with any of them.

Re: Radon Kits
I have the Sun Nuclear 1029's. As said before it has the built in tamper devices. Graphically displays everything with hourly readings. They also have the next model down called the 1028 if you are short on funds. Does not have as many tamper dectection parameters. It still graphically displays the levels with hourly readings. They are worth the consideration.

Re: Radon Kits
I think we paid about $800 each. Pretty simple. Put the key in, turn it on and let it run. It will sample every hour until you turn it off. You can get the report as a text file or graph. Both show hourly readings and average readings. It does not have settings for the 12 hour closed house conditions, the more expensive models do. They all have internal batteries and are said to run for 50 plus hours without power, but I've never tried it.

Re: Radon Kits
When you are selecting your equipment for radon testing, don't forget to factor in the cost of calibration and spiking. I have been using the EPERMS for years and currently have 9 sets of chambers. The beauty is I only have to calibrate one reader instead of multiple CRM's. I have a question for the CRM users....Other than a curiosity, do you use the individual hourly measurement data for anything? Or do you only report the average over the time elapsed?
Thanks

Re: Radon Kits
David,
I see you live in the same city as Rad Elec. That must be convenient.
I have used E-PERMs for several years and only recently started using a CRM (Sun Nuclear 1029) because some clients (e.g., relo companies) want only radon tests done with a CRM.
I report the average radon concentration as that is what we are interested in. I make no mention of high or low hourly readings UNLESS they are an indication of tampering or some other anomaly.

Re: Radon Kits
David;
What Bruce said is basically the same way we report.
