Our Laboratory

Short history.

Laboratory was created as radioecology lab of All Union Scientific Center of Radiation Medicine (AUSCRM) at October, 1, 1986 in Kiev. Head of lab is Ivan P. Los'. AUSCRM was renamed to Scientific Center of Radiation Medicine Academy of Medical Sciences of Ukraine.
At middle of 2000 lab as part of Radiation Hygiene Department was renamed to Radiation Hygiene monitoring lab. At March of 2003 lab was mooved to Marzeev Institute of Hygiene and Medical Ecology of Academy of Medical Sciences of Ukraine. Since then head of lab is Michael G. Buzinny.
