Igor Dvornik was a distinguished Croatian radiation chemist known for his significant contributions to the field of chemical dosimetry. He developed two original dosimetry systems based on ethanol-chlorobenzene solutions, with one system for high-doses being accepted as an ISO standard and widely utilized. Dvornik’s research into high hydrochloric acid yields in dosimeters led him to propose early theories regarding presolvated 'dry' electron reactions, marking important advancements in radiation chemistry.
