Latest information on Radon testing!


Effective June 4, 2013, HUD’s Office of Multifamily Housing new policy requires radon testing and, if applicable, mitigation for most new FHA-insured construction, conversion and substantial rehabilitation projects, as well as most FHA-insured refinance transactions.

Mallon Construction & Radon Services, covers the Cedar Valley area, and has installed over 1,000 mitigation systems in the last 20 years. For your convenience go to www.mallonconstructionandradon.com to order your test kit.

Agency for Toxic Substances and Disease Registry Radon Toxicity

Case Studies in Environmental Medicine (CSEM)

 The average person in the United States receives an

estimated 625 millirem/year dose from ionizing radiation.

The largest percentage is from medical radiation (48%, 300

mrem), primarily due to the popularity of CT scans and

Nuclear medicine. This is followed by radon (37%, 228

mrem), which is the largest source of background radiation.

While the dose from radon has remained the same over the

years, the percentage that it represents has dropped from

55%, based on 1980s data, to 37% using 2006 data. Due to

the increased use of certain medical procedures, this trend is

expected to continue (NCRP 2009). The dose of ionizing

radiation from radon comes from soil, water, natural gas,

and building materials.

The primary pathway for human exposure to radon is

inhalation from soil vapor intrusion into dwellings and

buildings. Indoor radon levels can, however, also originate

from water usage, outdoor air infiltration, and the presence

of building materials containing radium (EPA 2003).

Inhalation/ The main source of inhalation exposure is radon gas.

Reducing Radon Levels

Reducing #Radon Levels

Mitigation involves repairing or altering a building or building design for the purpose of reducing the concentration of radon in the indoor atmosphere.

Exact system design will vary from house to house dependent upon foundation type and building materials however most will consist of PVC pipe suction points attached to a fan pulling air from under the slab foundation or membrane and disposing of it above the highest eve of the roof. This system depressurizes the house in comparison to the outside environment, reducing the levels of soil gas (and radon) being drawn into the house.
