Radon in Schools: Despite state and federal recommendations, only 53 of 331 school districts in Minnesota report they have tested classrooms for radon since 2012. KARE 11 found out which Twin Cities area districts are testing – and which ones are not.

Hollywood recognizes Radon: Shantel VanSanten has turned a personal tragedy into a catalyst for helping others. After her grandmother passed, VanSanten and her family looked for answers, and were shocked at what they found. “We searched to understand what the cause was, and we found it was from radon poisoning, which was found in [her] basement.”

Vapor-Intrusion Assessments


Using Vapor Pins® for Vapor-Intrusion Assessments
The Vapor Pin® has a number of applications, but it was designed to collect soil gas for vapor-intrusion assessments, and it does it well. The soil gas directly beneath a building floor, “subslab” soil gas, best represents the risk of vapor-intrusion, because it is the next closest thing to indoor air. But unlike indoor air, subslab soil gas generally does not contain background contamination from indoor or outdoor sources. Subslab soil gas more representative of indoor conditions than deep soil gas, and it’s easier to collect using hand-held equipment.

Subslab soil gas is normally collected prior to sampling indoor air. One or more Vapor Pins® are installed by drilling 5/8-inch holes through the floor with a hammer drill, and installing them, as described in the Standard Operating Procedure (SOP). For a one-time sampling event, one can use brass Vapor Pins® installed in the stick-up configuration. If repeat sampling is needed, we recommend installing stainless-steel Vapor Pins® in the flush-mount configuration.

After installing the Vapor Pin® and allowing soil gas to equilibrate for two hours or more, connect the Summa canister, TO-17, or other sample container to the Vapor Pin®, purge the dead space in the sample train, and collect the sample, as described in the SOP. As discussed in the memorandum “Using Vapor Pins® for Source Characterization”, vapor sources are often located away from obvious locations, such as buried tanks and degreasing areas, so we recommend conducting field screening at additional locations when working near potential source areas.

Always follow the appropriate guidance when assessing vapor intrusion. Some regulatory agencies allow or encourage the use of the Vapor Pin®, but some guidance might preclude the use of some devices.
