In 2004, Helen Clark died from Cancer which her husband 'Henry believes developed as a result of her job at the National Semiconductor plant in Greenock'. 'Helen Clark spent six years working in production at National Semiconductor, operating a machine baking compounds on to silicon wafers using arsine gas, which contains arsenic.'
