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.
