Drwy gydol yr wythnos hon, mae pob awdurdod lleol wedi bod yn parhau i adolygu eu hystâd ysgolion er mwyn dod o hyd i unrhyw rannau a allai gynnwys RAAC. O ganlyniad i’r gwaith hwn, nodwyd dau achos pellach o RAAC mewn rhannau o ysgolion yng Nghymru.
Throughout this week, all local authorities have been continuing to review their school estate to identify any areas suspected of containing RAAC. As a result of this work, two further cases of RAAC have been identified in parts of schools in Wales.
