Yr wythnos diwethaf, cadarnhawyd gennym bod yr wybodaeth ddiweddaraf wedi dod i law gan bob un o'r 22 awdurdod lleol ar ddiwedd cam cyntaf y broses o ganfod RAAC mewn adeiladau addysg. Hyd yma, canfuwyd RAAC mewn pedair ysgol - dwy ar Ynys Môn, un yng Nghonwy ac un yn Sir Ddinbych.
Last week, we confirmed updates had been received from all 22 local authorities at the end of the first stage of the education RAAC identification process. To date, four schools have been identified with RAAC – two in Anglesey, one in Conwy and one in Denbighshire.
