Since you are in my same area I thought I would post.
This is from the EPA site:
EPA Recommends the Following Testing Steps:
**Step 1. Take a short-term test. If your result is 4 pCi/L or higher take a follow-up test (Step 2) to be sure.
**Step 2. Follow up with either a long-term test or a second short-term test:
- For a better understanding of your year-round average radon level, take a long-term test.
- If you need results quickly, take a second short-term test.
The higher your initial short-term test result, the more certain you can be that you should take a short-term rather than a long-term follow up test. If your first short-term test result is more than twice EPA’s 4 pCi/L action level, you should take a second short-term test immediately.
***Step 3. *If you followed up with a long-term test: Fix your home if your long-term test result is 4 pCi/L or more. If you followed up with a second short-term test: The higher your short-term results, the more certain you can be that you should fix your home. **Consider fixing your home if the average of your first and second test is 4 pCi/L or higher.
In regards to pricing.
My price depends on the location. If it is within 10 miles of my home I charge less.
If you use a CRM like radalink they charge a lease and per test fee. The nice features of Radalink is they do all the QA/QP & Calibrations and all the paperwork involved. There monitors read temperature, pressure and humidity and they provide free CEU recertification every 2 years.
If you have any questions I would be glad to talk to you on the phone or email.
