Radon Scare Forces HMP Dartmoor Prison Shutdown

HMP Dartmoor, a category C men’s prison in Devon, is shutting its doors temporarily. Hazardous radon gas has been found in several cells, prompting the evacuation of around 175 inmates over the next two weeks.

Prison System Under Massive Strain

The Ministry of Justice claims there’s enough room to relocate the prisoners, but the move piles more pressure on an already stretched UK jail system. Notably, those convicted of sex offences, terrorism, domestic abuse, or certain violent crimes won’t be moved.

Historical Jail Hit by Modern Health Crisis

Built in the early 19th century to house Napoleonic War prisoners, Dartmoor was set to close in 2023 but stayed open due to rising inmate numbers. Late last year, dangerous radon levels forced the removal of more than 400 inmates. Although some prisoners returned in July, this new radon discovery has shuttered the prison completely.

Prison Officers and MoJ Speak Out

Steve Gillan, general secretary of the Prison Officers’ Association, said conditions at Dartmoor had “deteriorated” since inmates returned but agreed that the closure was “the correct decision.” He warned overcrowding will worsen but added, “there is no other option.”

A Ministry of Justice spokesperson said, “Our prisons are in crisis. This incident shows why urgent action is needed to ease pressure on the estate. We remain committed to building new prison places to keep the most dangerous offenders off the streets.”

Jail Spaces Dangerously Low Amid Evacuation

Latest figures reveal fewer than 700 spaces remain in men’s prisons—well below the level needed to manage emergencies like this closure. As the evacuation unfolds, attention turns to maintaining safety for inmates and staff, while tackling the nationwide overcrowding crisis.
