I ended up smashing a medium sized hole in the plasterboard in my room earlier yesterday. Now I didn't use any protection whilst tearing out the various bits and then using polyfiler to close out the hole. I'm guessing I didn't expose myself to anything other than just some dust? There's no asbestos in these plasterboards?

I've been told modern plasterboards should not have any asbestos, however Pymers Mead was built in the 60s right? That's around the time when they still use to use asbestos in building materials, walls etc.
