Abstract : Use the researchers a way tray charcoal to absorb the radon gas from the air exposed, and then estimate the amount of radon absorbed by Adohah gamma of products decompose (lead - 214 and bismuth - 214) using a detector of pulsed sodium iodide and analyst multi-channel and isotope radium - 226 mm and also a program Kmpiotrmad to measure Radon in a box of coal. Has offered more than a pack a double coal indoor air in different buildings in the area of ​​Jeddah and the duration of exposure for six days, then close the tray a good coal, and after a short delay of gamma rays measured by. It was found that radon concentrations obtained by the researchers are as follows: 37% of the samples with concentration ranging between zero - 0.5 pico Curies / liter. 32% of the samples the concentration range of 0.5 - 1 pico Curies / liter. 26% of the samples with concentration ranging between 1 - 1.5 pico Curies / liter. 4% of the samples with concentration ranging between 1.5 - 2 pico Curies / liter. There are a few samples with concentration ranging between 2 - 2.5 pico Curies / liter. All of these concentrations of radon gas inside buildings that reveal the inside of Jeddah, is less than 4 Peacocuori / L, which has come to be considered as an end requires him to do the procedures to reduce the radon concentration procedure, that is, it seems to be no danger there is the likelihood of the presence of high concentrations of radon in buildings Jeddah revealed by them.
