Abstract Objective To explore the variation of complete blood count of maintenance workers in a nuclear power plant.Methods Analysis of variance was used to analyze the repeated measurement data and evaluate whether the counts of red blood cells, white blood cells and platelets have changed over the years, whether differences in blood cell counts among workers of different ages were significant, and whether age is associated with time.Results Erythrocyte counts of nuclear power plant maintenance workers changed over time (F = 40.89, P < 0.001), and time was associated with age (F = 3.74, P = 0.005); Leukocyte count changed over time (F = 5.78, P < 0.001), and time was not associated with age (F = 0.77, P = 0.578); Platelet counts changed over time (F = 30.37, P < 0.001), and time was not related to age (F = 0.67, P = 0.668). There was no difference in erythrocyte, leukocyte and platelet counts among workers of different ages (P > 0.05).Conclusion The number of blood cells of nuclear power plant maintenance workers decreased at first and increased to a higher level. Further study is needed to better understand the phenomenon.
