All Black Dog Radon Services radon tests are performed by AARST NRPP measurement certified personnel. We typically use Continuous Radon Monitors (CRM) for short term radon testing. Black Dog Radon Services can use the Sun Nuclear models 1028XP and 1030 for quick turn around reports. Once the test is completed the data can be down loaded to a computer to provide the results. These particular units (Sun 1028XP & 1030) require a seperate analytical certification for each device.
