Radon testing and management is not a regulated activity in Minnesota. Given the unique properties of radon gas, it is important to be aware of the risks associated with prolonged exposure to high levels and to be proactive in its control.
This management plan has been developed to address aspects of radon gas within the St Cloud School District thereby assuring the students and staff of a safe and healthy learning and working environment. The recommendations contained in the plan are based on the recommendations of the US Environmental Protection Agency and the Minnesota Department of Health. Because radon is known to cause cancer and is a cause of lung cancer, second only to tobacco smoking, it is important that possible radon exposure be determined and controlled.
As written, this plan is intended to guide the St Cloud School District in its efforts to provide a safe and healthy environment in which to learn, but will need to be reviewed and modified on a regular basis. The St Cloud School District is responsible for the enforcement and updating of the plan. Actual use of the plan is limited to Resource Training & Solutions and to the St Cloud School District that it represents.
Radon Management Plan Review & Update Report
Program review and changes are documented below. Documented reviews indicate that the plan continues to meet the needs of the District, or has been modified to do so more effectively.

Radon is a naturally occurring, radioactive gas that enters buildings from surrounding soil. It is a colorless, odorless, tasteless, radioactive gas, the primary source of ionizing radiation to humans. The level of radon gas present in an area may pose a health hazard to students and staff alike. Testing is the only way to determine how much radon is present in the school, though it is estimated that radon levels in schools are relatively low. Test results are measured in picoCuries/liter (pCi/L) which are used to establish the action levels recommended by the EPA.
The recommendations in this plan reflect unique aspects of the radon levels typical in Minnesota which may be affected by climate, geology and the lack of ventilation in unused areas, such as crawl spaces, tunnels and below-ground level storage areas and classrooms. This management plan has been written to help the St Cloud School District determine where a radon problem may exist and to provide guidance in steps determine the levels of exposure. If action levels meet or exceed recommendations by the EPA, this plan provides step-by-step procedures for remediation most importantly relying on proper ventilation.
Action level - the EPA recommended action level of radon is 4.0 pCi/L
Closed conditions - all doors and windows maintained in a closed position, air exchange systems turned off, initiated at least 12 hours before testing is initiated
Ionizing radiation - harms the cells that make up our body's tissues and organs
Long-term tests - testing over a period of at least 90 days (Alpha Track Detector or "ATD")
picoCuries/liter (pCi/L) - the level of radon present in the measurement area
Radon - an odorless, tasteless, colorless, radioactive gas which is the number two cause of lung cancer in humans; primary source of ionizing radiation
Short-term tests - a screening test over a period of 2 to 7 days in closed conditions (charcoal canister)
Mike Machacek or the designated employee of the St Cloud School District has been trained in the requirements of this plan and is responsible for implementation and upgrading the plan. Responsibilities include, but are not limited, to:
B. Testing Materials
C. Assessment and Mitigation
If the results of testing indicate a level of radon presence above 4 pCi/L, St Cloud School District will take steps to lower the levels. The source of radon will dictate the type of remediation that takes place, i.e., increased ventilation, repair of cracks in concrete, covering exposed soil in crawl spaces.
The St Cloud School District will provide training and support to affected staff to inform them of the risks of radon gas, testing and remediation.
The St Cloud School District will maintain all testing records and any correspondence with regulatory agencies regarding radon gas as well as records of all training provided to affected staff.

The following checklist serves as a quick reference for the St Cloud School District to evaluate their level of compliance.
Note: This checklist is not intended to be comprehensive in nature. The St Cloud School District should refer to their respective Exposure Control Plan which further outlines general compliance requirements.

123B.571 RADON TESTING.
Subdivision 1.Voluntary plan.
The commissioners of health and education may jointly develop a plan to encourage school districts to accurately and efficiently test for the presence of radon in public school buildings serving students in kindergarten through grade 12. To the extent possible, the commissioners shall base the plan on the standards established by the United States Environmental Protection Agency.
§Subd. 2. Radon testing.
A school district may include radon testing as a part of its health and safety plan. If a school district receives authority to use health and safety revenue to conduct radon testing, the district shall conduct the testing according to the radon testing plan developed by the commissioners of health and education.
Subd. 3. Reporting.
A school district that has tested its school buildings for the presence of radon shall report the results of its tests to the Department of Health in a form and manner prescribed by the commissioner of health. A school district that has tested for the presence of radon shall also report the results of its testing at a school board meeting.
