"Disposable see-thru X-ray gowns"

Went for an ultrasound. Putting on gown (disposable), I noticed it was see-thru, confirmed by mirror. I was stunned. I was not going to expose myself to the radiographer, so I put on 2 gowns. Then the strap broke when I went to tie up (extra cheap), so I  had to remove both gowns, and reverse order. When I complained to Healthcare Imaging they said they investigated and that it did not display the transparency which I described. When I queried that, and the investigation, they replied they were not going to take my complaint further. I offered to come in and have it witnessed - denied. I offered to buy a gown - denied. I asked for details of gown so I could make my own complaints to manufacturer or supplier etc... but they refused to give me details. Company says it meets Australian  Standards. If see -thru x-ray gowns are acceptable standard in Australia, I want to complain! Women and girls deserve better.
