摘要:

The effects of pre irradiation with γ-ray prior to thermal decomposition on the induction period of hexammine cobaldt (III) chloride have been investigated. The results indicated that the induction period of the investigated salt is shortened by exposure to γ-irradiation. Specifically the induction period I is related to the radiation dose by the equation I = C1+ C2log Φ, where C1and C2are constants. It is concluded that pre-exposure to ionizing radiation increases the number of nuclei that are active in salt breakdown in direct proportion to the γ-dose to which the sample had previously been exposed.

摘要:

The publication shows the radiological measurements of rain water, cress, and milk before and after Chernobyl nuclear power accident. The measurements showed that Egyptian environment was affected by the accident, but the increase of radioactive contamination was small and below the permissible. The paper suggests methodological procedures for measuring the growth activity in the studied materials. It offers also a simplified diagram for automatic national radiological monitoring station to measure the environmental background radiation by a routine way for detection any increase of radioactivity rapidly. This station enables the responsibles to take rapid and optimum decisions in time to lessen the environmental radiological contamination.
