The Electrical Trades Union is seeking to ban its members from contributing to the proposed nuclear waste dump in Central Australia.

The ETU used its Northern Territory delegates conference in Darwin yesterday to discuss the union's concerns about the proposed nuclear waste site.

The ban would stop union members from participating in any work related to the uranium industry, especially a nuclear dump at Muckaty Station if it is approved.

The union will tell a Senate Committee it opposes the dump proposal.

The ETU says it considers uranium to be the new asbestos and it has long been concerned about the dangers of working with radioactive waste.

The union says it received strong initial support for the ban from delegates and will now seek votes from Northern Territory and Queensland members.

Trevor Gauld from the ETU says the organisation is disappointed with the lack of public consultation about the project and it will make that clear to the comittee when it comes to Darwin.

"If they can make these decisions overnight without including anyone, without taking any regard to the communities that they are enforcing these decisions into, when's it going to be my backyard that's going to have this thrown in the back of it?" he said.

"What are they going to try to put in my backyard next?"
