best practise radio buttons

Hi all,
 
I would be grateful for some advice in best methods for making radio buttons accessible. I have a need to set part of a survey out as illustrated on the follwing http://www31.brinkster.com/atennant/dda_radio_buttons.html
 
Although the page could be redesigned to avoid the layout of radio buttons this is the requested design and I want to try and accommodate it.
 
One technique I was considering is having text after each radio button marking it up with <labels> and using css to hide the text. Another technique I have read is to add title tags to each radio button.
 
Does anyone have good examples of trying to do this type of layout and techniques used. Any help would be appreciated.
 
Many thanks
