The role of thorium in endomyocardial fibrosis

Abstract

The behaviour of thorium in animals exposed through injection, ingestion and inhalation, as well as in uranium miners, millers and the general population suggests that thorium accumulates primarily in the lung, tracheobronchial lymph nodes and skeleton; or in the liver if injected with polymeric thorium. Epidemiological studies on uranium miners, Thorotrast studies in man and animal, and studies on the toxic effects of thorium in animals suggest that there is no apparent heart diseases due to exposure to thorium in man and animal.
