Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of 222RN from phosphate fertilizers, clay and potatoes in...

PURPOSE/OBJECTIVES To gather data on radon levels and determine correlations among subjects' characteristics, willingness to test for radon, and perceptions of radon as a health risk. DESIGN Descriptive correlational. SETTING Rural DeKalb County in northern Illinois. SAMPLE 473 respondents from a group of 1,620 randomly selected county residences. METHODS Participants were surveyed via ...

Argonne National Laboratory (ANL) recently discovered that a class of inexpensive and biologically benign fluids absorb radon gas with a high efficiency at room temperature, and release radon at slightly elevated temperatures (50-60 OC). This has led to the development of simple and inexpensive devices for continuous removal of radon from air. Such devices offer numerous advantages over convent...

OBJECTIVE Uranium miners are chronically exposed to low levels of radon and its progeny. We investigated whether radon exposure is associated with increased incidence of leukemia, lymphoma, or multiple myeloma in this population. DESIGN We conducted a retrospective case-cohort study in 23,043 uranium miners and identified a total of 177 incident cases of leukemia, lymphoma, and myeloma. Detai...

BACKGROUND Ventilator exhalation-valve performance during the expiratory phase has been studied in depth. An active exhalation valve uses servo-control technology that allows gas to be released from the exhalation valve during the inspiratory phase if the patient makes an expiratory effort. We conducted a bench study of active exhalation valve response to expiratory effort during the inspirator...

BACKGROUND Indoor radon has been determined to be the second leading cause of lung cancer after tobacco smoking. There is an increasing need among radiation practitioners to have numerical values of lung cancer risks for men and women, ever-smokers and never-smokers exposed to radon in homes. This study evaluates individual risks for the Canadian population exposed to radon in homes at differen...
