[en] The mineralogy of secondary uranium minerals in the Judean Desert (central Israel) and in the northern Negev is discussed and summarized. Their occurrence is of two types: type a, uranium mineralization in the Hatrurim Formation ('Mottled Zone'); and type b, uranium mineralization in soils. In both types the uranium minerals are associated with gypsum layers, crusts and veins. Uranium minerals identified were carnotite, meta-autunite, metatyuyamunite, tyuyamunite, bayleyite, saleeite, rauvite, zellerite, autunite and phosphuranylite(?). Most of these minerals had not been previously identified in the region. The source rocks for the U-bearing minerals were phosphorites and metamorphosed phosphorites and bituminous chalks and marls of Senonian to Paleocene age that are widespread in this area. It is postulated that U was leached out of these rocks by meteoric waters and migrated towards the Dead Sea Rift Valley where it was concentrated by evaporation under oxidizing arid conditions. The most prominent concentration of U was observed in the margins of the Hatrurim syncline. 19 refs.; 2 figs.; 1 plate

[en] Nuclear technology and nuclear energy in Israel and in other countries as well, are suffering from 'bad reputation', originating from both ignorance and misleading publicity. In order to provide the public, and especially the young generation, with objective and comprehensive facts and data, the Israeli Atomic Energy Commission (IAEC), and the Nuclear Research Center - Negev (NRCN) decided to create a permanent exhibition in Beer Sheva, covering Nuclear Technology. Similar activity was done in other countries, such as France, Slovenia and others.

[en] Rainfall at two stations in the Shephela (Israel Coastal Plain) was analyzed for ²¹⁰Pb during the winter of 1974-75. The highest concentrations of ²¹⁰Pb were found in samples collected early in the rainy season. It seemed that there was a small, but significant difference between the two stations. The total activity at the Bet-Dagan station (near Tel-Aviv) and generally also the activities in the individual samples collected at this station were lower than the respective activities at the Gan-Shomron station (60 kms to the north)
