Impact of chronic blood viral infection on lymphocyte telomere length in Chornobyl clean-up workers in a remote period after radiation exposure.

Objective: To assess whether telomere length in lymphocytes of Chornobyl clean up workers at a late period 30 years after the exposure to ionizing radiation is influenced by a chronic blood viral infection and to determine role of viral carriage in cellular senescence.

Patients And Methods: Study group included 70 Chornobyl cleanup male workers 30 years after exposure {doses of external exposure (602.67 ± 114.
