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...

Azinphosmethyl (APM) is one of the most common insecticides used in fruit farming. The object of this paper is to develop a quick and practical test for assessing the risk for humans coming into contact with APM.

METHODS Departmental work history records, along with data on historical annual fire-runs and hours, were collected from 1950 to 2009 and coded into separate databases. These data we...
