Measurement of radon is very important in dwellings because of its radiological impact on public health. Radon contributes more than half of the total ionizing radiation dose. It is known from the recent surveys in many countries that radon is the second cause of lungs cancer after smoking. In this context, we have measured radon ( 222 Rn) concentration in different dwellings of Kathmandu valle...

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 The current study aims to assess the radon concentration in blood serum of lung cancer patients Babylon governorate and compared measured values healthy people. Radon ( 222 Rn) is one typical alpha-particle emitters. Cancer cases, especially cancer, have been increased a notable way Governorate particularly after gulf wars 1991 2003. So, measuring gas important find out relations betwe...

Chhatrapur beach placer deposit, situated in a part of the eastern coast of Orissa, is a newly discovered high natural background radiation area (HBRA) in India. The sand samples containing heavy minerals, were collected from Chhatrapur region by the grab sampling method at an interval of ~ 1 Km. Radon exhalation rates were measured by "Sealed Can Technique" using LR-115 type type II in the san...

INTRODUCTION The rising public wish for natural residing, new rules for energy and resource saving construction and the interest of the industry on inexpensive raw materials lead to new developments in the field of building materials. In this connection, the isolation of buildings against radon, especially in radon prone areas, shows an inclining interest. A recent German case control study on ...
