The existing cell phone certification process uses a plastic model of the head called the Specific Anthropomorphic Mannequin (SAM), representing the top 10% of U.S. military recruits in 1989 and greatly underestimating the Specific Absorption Rate (SAR) for typical mobile phone users, especially children. A superior computer simulation certification process(More)
OBJECTIVES We examined temporal trends, spatial variation, and gender differences in rates of hospitalization due to acute myocardial infarction. METHODS We used data from the Centers for Disease Control National Environmental Public Health Tracking Network to evaluate temporal trends, geographic variation, and gender differences in 20 Environmental(More)
BACKGROUND The capacity of radiofrequency from cell phones to be absorbed into the brain has prompted concerns that regular cell phone use may increase the risk of acoustic neuroma (AN) and other brain tumors. This article critically evaluates current literature on cell phone use and AN risks and proposes additional studies to clarify any possible linkage.(More)
OBJECT The authors evaluated the potential role of environmental risk factors, including exposure to diagnostic or therapeutic radiation and to wireless phones that emit nonionizing radiation, in the etiology of vestibular schwannoma (VS). METHODS A total of 343 patients with VSs who underwent Gamma Knife surgery performed between 1997 and 2007 were age(More)
Increased evidence suggests that folate may play a significant role in cancer development. This study investigates the association between levels of serum folate and prostate-specific antigen (PSA), a biomarker for prostate cancer detection. Using data from the 2007 to 2010 National Health and Nutrition Examination Survey, a total of 3,293 men aged 40 years(More)
