In this study, the radon gas concentration as well as the annual effective dose in leaves of the Malvasylvestris (Khabbaz) plant used in the traditional treatment and as food in Iraq, for this, it is necessary to evaluate the concentrations radon gas, which were measured using solid state nuclear track detectors (SSNTDs) CR-39 technique. The Rn222 concentration and annual effective dose in samples were collected from Baghdad city ranged from minimum to maximum value 15.815(Bqm3⁄), 0.498(????????????????−1), 54.445(Bqm3⁄), 1.717(????????????????−1) respectively, while the values of Rn222 concentration and annual effective dose in a sample collected from Karbala are 15.297(Bqm3⁄),0.482(????????????????−1). These values of Rn222 concentration and annual effective dose less were compared with the samples from Baghdad. The annual effective dose lies well within the safe limits as recommended by WHO. So, the uses of Malvasylvestris plant are in traditional medicine and as a safe food for human consumption.
