Development of hypertension after long-term exposure to static magnetic fields among workers from a magnetic resonance imaging device manufacturing facility

Highlights: • High cumulative exposure to MRI-related static magnetic fields is associated with hypertension. • No association was apparent for low cumulative exposure to static magnetic fields. • New association pointing at long term effects of static magnetic fields needs corroboration. To assess the association between long-term exposure to static magnetic fields (SMF) in a magnetic resonance imaging (MRI)-manufacturing environment and hypertension.
