Background: Radon concentration was measured in the soil and indoor of Amman and Al- Rusaifa cities in Jordan during summer season. Materials and Methods: The measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as CR-39. Results: Radon concentration levels in the soil ranged from 2.8 ± 1...
Abstract Background and purpose: People are always exposed to ionizing radiation, which could badly influence their health. The degree of these influences depends on the level of radiations. In this study the dose of indoor gamma radiation was assessed using RDS-110 Multi-purpose Survey Meter. Materials and methods: To determine the dose rate of indoor radiations in cities of Hamedan provi...
