The Washington State Department of Health Radon Program recommends that schools test and reduce exposure to elevated levels of radon, and locations such as child care centers where children spend a considerable amount of time so do also.
To provide guidance and encourage awareness of possible exposures to radon in schools and child care centers, the department provides written information as well as an interactive map of the state.
An online brochure, “Eco Health Child Care,” provides information about radon health effects, testing and discusses exposure in the child care setting. https://cehn.org/wp-content/uploads/2017/03/Radon_3_17_final.pdf
An interactive map shows three radon risk zones based on the underlying geology (both bedrock and soils). A Feature Map Layer from the menu shows locations of child care centers and K-12 schools. The map shows the potential to be exposed to radon based on characteristics of the surface geology:
• High, geology contains uranium, or has rock types known to contain uranium.
• Medium (variable), geology may have uranium containing rock deposited from glacial or other events.
• Low, geology or soil type unlikely to contain uranium.
