Abstract
The study concerns with the safe application of geological raw materials in industries of ceramics and natural fertilizer as agricultural soil for planting. In both cases the controlled factors of applications are the secure impacts on environment and human health. Experiments and spectrometric measurements were performed to select the most optimum materials from the radioactive dose rate and radiogenic points of view and for domestic indoor and outdoor uses. K-feldspars are the main raw materials for use in ceramic industries. The supplies of K-feldspars are best coming from the stream sediments of Wadis crossing the plutons of alkali feldspar granites Spectrometric survey was carried out in this work to obtain the distribution of the radioelements (K, U and Th) and total radioactivity. Almost values of specific activity per unit mass for the raw materials quarried from Abo Zawal, El Missikat and Homret El Gergab are higher than the permissible limits in the typical world values, 500, 50 and 50 Bq.kg-1 for Ck, CRa and CTh respectively (NEA, 1979). Also, almost values of exposure rate and effective dose rate of these raw materials are higher than the value of permissible effective dose limit ”1.0 mSv/y” recommended by the International Commission on Radiological Protection by many folds of values. Therefore, these raw materials actually are un-conventional for using in the ceramic and natural fertilizers.On the other hand the same parameters (e.g. specific activity and effective dose rate) for the raw materials of Wadi El Dahl and Wadi El Esh are less than unity and are considered as safe sources for the raw materials used in ceramic and natural elements compound fertilizer industries. Five crops namely: wheat, sugar beet, tomatoes, Volkamariana rootstocks and Navel orange are the plant material used in this work during two cultivating seasons. This part of study concerns with the response of these plants to Natural Elements Compound soil application as natural fertilizers in compared with chemical fertilizers. Since, vegetative growth parameters of plants, yield and crop quality are the main points subjected to investigation in this respect. In general speaking the Natural Elements Compound has more efficient for the soil minerals content, safe for health impact, improvement of plant growth and yield production when compared with the individual chemical fertilizer applications.
