Crown Censure authorised at HMP Dartmoor

Friday 15th May 2026

The Health and Safety Executive (HSE) has announced their intention to serve HMP Dartmoor with a Crown Censure as a result of radon exposure.

The HSE has been monitoring exposure since February 2023 and found that several areas of the prison were over the legal limit. The investigation concluded that both prisoners and staff had been exposed to radon significantly above the specified dose limits for an extended period of time.

A hearing will take place to confirm the Crown Censure, and if confirmed, will provide a public record of the prisoner’s failure to comply with the law.
