Commercial Radon Monitor Placement and Cost:
Larger commercial buildings that require many monitors are subject to variable pricing based upon building size, area, and applicable measurement regulations. Please call for more information and to receive quote for your project.
Commercial radon measurement reports are accompanied with a Standard Operating Procedure for the performance of the Day Care Center, commercial building or School building measurement. (IEMA Measurement Protocol, Section 422.130 of 32 Ill. Adm. Code 422. (g)).
See below for the measurement terms that determine the cost of a commercial radon measurement:
1. Initial measurements shall be short-term measurements of at least 48 hours to 90 days, depending on the device used, and shall be made in all frequently occupied rooms in contact with the soil, whether the contact is slab-on-grade, a basement, berm, a room above a crawlspace or any combination.
A. Frequently occupied rooms include classrooms, offices, conference rooms, gymnasiums, auditoriums, cafeterias and break rooms.
B. Testing need not be conducted in infrequently used areas such as storage rooms, stairwells, restrooms, utility closets, elevator shafts or hallways.
C. A minimum of one detector shall be placed per every 2000 square feet of open floor area.
D. Schools and commercial buildings shall only be tested for radon during periods when the HVAC system is operating as it does normally when the buildings are occupied, even if the testing occurs when school is not in session or during long holidays.
2. All frequently occupied rooms shall be tested simultaneously.
3. Follow-up measurements shall be performed in every room with a short-term, initial measurement result of 4.0 pCi/L or greater.
4. During both initial and follow-up measurements, the HVAC system shall be operated normally.
5. School and commercial building measurements shall be performed in accordance with subsections (a) and (b).
A. School and commercial building measurements of less than 96 hours duration shall be performed under closed-building conditions as described in subsection (b)(1).
6. Requirements for Specific School and Commercial Building Designs
A. Slab-on-Grade Design. Measure all frequently-occupied rooms in contact with the ground.
B. Open-Plan or Pod Design. If sections of a pod have movable walls that can physically separate them from other sections, measure each section separately. If movable walls are absent or inoperable, measure the pod as one room placing detectors every 2000 square feet.
C. Crawlspace Design. Measure all rooms directly above an enclosed crawlspace.
D. Basement Design. In addition to measuring all frequently-occupied basement rooms, measure all frequently occupied rooms above the basement that have at least one wall with substantial contact with the ground.
7. Quality control
A . Duplicate measurements shall be performed and shall represent 10 percent of all the detectors deployed, or a maximum of 50 detectors, whichever is less, within the building.
B. Blank measurements shall be performed and shall represent 5 percent of all the detectors deployed, or a maximum of 25 detectors, whichever is less, within the building.
8. The on-site presence of the Licensed Radon Measurement Professional providing supervision is required for
all radon measurement activities at schools and commercial buildings.

A. All measurements are performed in accordance with IEMA Measurement Protocol, Section 422.130 of 32 Ill. Adm. Code 422.
Residential Radon Monitor Placement:
A. When area of the home being measured is over 2000 Sq.Ft., an additional measurement location is required for each 2000 Sq.Ft. of the area being measured. (IEMA measurement Protocol, Section 422.130 (a) (1) (c) of the 32 Ill. Adm Code 422)
1. A minimum of one monitor to be placed for every 2000 square feet of open floor area
2. Additional monitors are required in areas greater than 2000 square feet and according to building use and design.
Requirements for Multi-family building Design:
Slab-on-Grade Design. Measure a regularly-occupied room in each unit in contact with the ground.
Crawlspace Design. Measure a regularly-occupied room directly in each unit above an enclosed crawlspace.
Basement Design. In addition to measuring a regularly-occupied basement room in each unit, measure a regularly-occupied room in each unit above the basement that has at least one wall with substantial contact with the ground.
