A new poll suggests a majority of Australians are against the export of uranium to countries that have nuclear weapons.

The Newspoll, commissioned by the Australian Conservation Foundation, surveyed 1200 people nationally last weekend.

Sixty-two per cent are against exporting uranium to countries with nuclear weapons and 40 per cent oppose its export for use in electricity generation.

The ACF's David Noonan says the poll is aimed at giving the Government and mining companies an indication of people's attitudes.

"We're looking to pressure BHP and Rio Tinto on their plans to export uranium to China," he said.

"We're looking to put a lot of clear community expectations in the way of Rudd Labor Government considerations to signing on in future to the proposed Russian deal that [John] Howard and [former Russian president Vladimir] Putin put forward before the federal election," he said.
