The information about the radiation risk of non-cancer respiratory diseases is inconsistent and mainly corresponds to mortality. Previously, an increased risk of chronic bronchitis incidence was demonstrated in the cohort of workers employed at the first Russian nuclear facility Mayak Production Association who had been chronically exposed to gamma rays (externally) and to alpha-active plutonium aerosols (internally). Within this retrospective study, we performed analyses of incidence of and mortality from chronic bronchitis and bronchial asthma using improved estimates of radiation doses provided by the "Mayak Worker Dosimetry System (MWDS) - 2013".

- Workers at the Mayak Production Association faced increased risks of liver cancers due to chronic exposure to gamma rays and inhalation of plutonium, leading to updated assessments of liver malignancies from 1948 to 2018.
- The study analyzed 62 liver malignancies and found a significant link between internal exposure to alpha radiation and the risk of various liver cancers, particularly hepatocellular carcinoma.
- No correlation was found between external gamma-ray exposure and liver cancer rates, and gallbladder cancer incidence showed no association with occupational radiation exposure.
Article Synopsis
- Cardiovascular disease (CVD) is the top cause of death globally, with radiation exposure linked to increased CVD risk, but research shows varying results due to potential confounding factors.
- The study analyzed 43 epidemiological studies to see how lifestyle, environmental, and medical risk factors affect the relationship between radiation and CVD.
- Only a few studies indicated significant adjustments for these confounding factors, pointing to ongoing uncertainty about how much these variables actually influence radiation-associated CVD risks.
The aim of the present study was to assess the risk of primary central nervous system (CNS) tumour incidence in a cohort of 22,377 Mayak Production Association workers chronically exposed to ionising radiation. There were 96 primary CNS tumours, including 42 cases of glioma and 44 cases of meningioma, registered during the whole follow-up period (1948-2018). The study demonstrated that the risk of primary CNS tumour incidence was associated with sex, attained age, calendar period, tall body height, age at the beginning of exposure, and facility type.

The relative uncertainty (U) of the threshold dose was estimated using the error propagation technique. The quantile technique provided statistically significant estimates of threshold doses for acute radiation syndrome onset (0.
