ABSTRACT
Background: Most lantern mantles contain low levels of radioactive thorium. Although radioactive lantern mantles present a minimal radiation health hazard, it is generally believed when inhaled or ingested, it can be dangerous. The purpose of this study was to assess the effect of short term exposure to radioactive lantern mantle on serum cortisol level and blood count.Materials and Methods: This experimental study was conducted in 2007-2009 in the school of medicine of Rafsanjan University of Medical Sciences. Twenty eight rats were divided randomly into two groups of 14 animals each. The first group was exposed to 600 mg burned radioactive lantern mantle powder (activity of 800Bq) for 24 hours and inhaled radon released from mantles. The second group was exposed to non-radioactive lantern mantle powder at the same interval. Paired t-test was used to evaluate the difference in the means of cortisol and blood cell count in both groups. P
