PHYSICO-CHEMICAL CHANGES INDUCED BY y-IRRADIATION IN SOME COMPOUNDS OF MEDICAL AND BIOLOGICAL ACTIVITIES.

Abstract

In recent ve rs metalo-organic and nrganrc materials arc used widclv. These materials can suOcr considerable radiation d;unagc during their nperatinnal lives and •;I is obviously imporl nl In know the eficcls of radiation on their phvsicl bcha,•inr

There is considcr ble intcrcst•tn study the phvsico­ chcmicl properties (ll fcrroccne i his (cyclopcnt clienyl) iron: Cd J,)2Fc l. l'ipcracillin: C 21 11 2 r.N<07SNa and Endoxan (cyclnphosphamide):C7JI,CJ.2 N2021)1120. Also. In invcstig tc the cflcct nfy-irradi tinn on their properties.
