The study evaluates the hazards of background radiation and Cesium- 137 in the soil of greenhouses within the region of Riyadh, Saudi Arabia. The Mole detector was utilized. It renders readings for the concentration of Uranium- 238, Thorium- 232, Potassium- 40 and Cesium- 137. Field measures were conducted at Alkharj at Nowara Farm Nurseries, Saudi Arabia. Measures were taken at three different greenhouses (plastic covered, glass covered and fiber glass covered). The plants at the plastic- covered greenhouse were cucumber, pepper and eggplant while in the glass and fiber glass- covered greenhouse, the vegetation were ornamental plants and flowers. The average concentration of Uranium- 238 recorded (19.33 Bq/ kg), Thorium- 232 (14.09 Bq/ kg), Potassium- 40 (130.77 Bq/ kg) and Cesium- 137 (1.81 Bq/ kg). These values are less than the world rates. Some radiation hazard indices were also calculated like Radium Equivalent (Raeq), the absorbed dose of Gamma rays in the air, external and internal hazard indices with the purpose of evaluating the dangers of the radiations existing in the greenhouse soil on health. The average radium equivalent activity (Raeq) recorded (49.56 Bq/ kg) which is less than the permissible world rates (370 Bq/ kg). The absorbed dose of Gamma rays in the air recorded (22.94 nGy/ hr) which is again less than the permissible world rates (59 nGy/ h). The average internal and external hazard indices recorded less than one and came within the world permissible limits.

A source of gamma rays has been found at right ascension 20h15m, declination +35°, with an uncertainty of 6° in each coordinate. Its flux is (1·5 ± 0·8) x 10-4photons cm-2sec-1at 100 MeV. Possible identifications are reviewed, but no conclusion is reached. The mechanism producing the radiation is also uncertain.

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
