RMIT staff don radiation level monitors

Workers on the top floor of RMIT's Bourke Street campus have begun wearing devices to monitor radiation levels.

Ten staff are still refusing to work in that part of the building, after a string of cancer cases came to light earlier this year.

Tests have ruled out any environmental cause and most staff have gone back to work.

Jeanette Pierce, from the National Tertiary Education Union, welcomes the mobile devices.

She says they are better than the spot testing done up until now.

"Although they did turn on lights and computers it wasn't a normal working environment and so this will be more of an ongoing type testing rather than just of a time and place," Ms Pierce said.

RMIT's Steve Somogyi says the university is also fulfilling its commitment to conduct ongoing tests.

"We're just about to do that first six-monthly check on the environmental measures," he said.

"That'll be done in the next two or three weeks.

"There is only a few more reports yet to come on both the environmental results and the epidemiology results."
