Association between cumulative radiation dose and haematological parameters among Korean radiation workers: a retrospective cohort study.

ABSTRACT:

Objective

To evaluate the association between cumulative radiation dose and haematological parameters among radiation workers and compare the prevalences of abnormalities in blood counts with those in the general population.

Design

Retrospective cohort study.

Setting

Nationwide radiation dose registry in Korea, linked with occupational health examination data. Cumulative doses were estimated using annual personal dose equivalent (H_p(10)) records from 1984 onward.

Participants

The study included 20 414 radiation workers, comprising 17 651 men (86.5%) and 2763 women (13.5%), with baseline survey data, dosimetry records and at least one complete blood count (CBC) record between 2014 and 2019.
