The aim of this study was to investigate the mean survival time for Chernobyl clean-up workers (liquidators) with diagnosed solid cancer. The cohort of liquidators contained 142871 males who worked in the Chernobyl exclusion zone from 1986–1987. The number of overall death cases among those liquidators was 5085 (4351 deaths were due to cancer). Mean survival time for liquidators after the diagnosis of solid cancer and documented tumor stages between 2000 over 2015 was 4.73 years.

Two dose groups were identified: group 0–100 mGy (average dose: 56.6 mGy) and group 100+ mGy (average dose: 187.9 mGy). Mean survival time was 4.66 and 4.72 years and the difference between the values was insignificant.

二つの線量集団、即ち、0~100 mGyの集団(平均線量:56.6 mGy)と100 + mGyの集団(平均線量:187.9 mGy)が特定された。平均生存期間は4.66年と4.72年であり、その違いはわずかであった。
