The chemical consequences following the formation of inner-shell electron vacancies in Br atoms of solid 5-bromodeoxyuridine (BUdR), induced by monoenergetic fluorescence x-rays, were studied by means of ESR technique. The radical concentration per unit dose absorbed was determined as a function of x-ray energy. For BUdR it exhibits a resonance increase near the K-absorption edge of Br, while it remains constant in thymidine (TdR). The radiation chemical resonance effect can clearly be attributed to the consequences of the Auger effect. The results seem to indicate that Auger charging and subsequent molecular fragmentation rather than electron self-radiolysis is responsible for the observed damage.
