Cafwyd mynediad at fanylion mwy na 3,400 o staff y GIG a mwy na 1,300 o staff nad ydynt yn gweithio i’r GIG. Roedd yr wybodaeth am yr unigolion hyn y cafwyd mynediad ati yn cynnwys y manylion a ganlyn - enwau, dyddiadau geni, dosau o ymbelydredd a rhifau Yswiriant Gwladol. Mae Byrddau ac Ymddiriedolaethau Iechyd wedi cadarnhau bod pob aelod o staff y GIG y bu modd iddynt eu hadnabod naill ai wedi cael gwybod eisoes, neu y byddant yn cael gwybod erbyn diwedd yr wythnos. Mae prosesau ar waith i hysbysu cyn-weithwyr y GIG sydd wedi cael eu heffeithio a gweithwyr cyrff nad ydynt yn perthyn i’r GIG sydd wedi cael eu heffeithio. Rwyf wedi gofyn am sicrwydd gan bob Bwrdd ac Ymddiriedolaeth y bydd cymorth yn cael ei roi i’r rheini yr effeithiwyd arnynt ac y bydd camau yn cael eu cymryd hefyd i dawelu meddyliau'r rheini na chafodd eu manylion eu gweld.
The details of over 3,400 NHS staff and over 1,300 non-NHS staff were accessed. The information accessed on individuals was a combination of some or all of the following - names, dates of birth, radiation doses and National Insurance numbers. Health Boards and Trusts have confirmed that all NHS staff that they have been able to identify have either already been notified, or will be notified, by the end of the week. Processes are in place to notify former NHS employees affected and non-NHS staff affected. I have sought assurances from all Boards and Trusts that support will be provided to those affected and reassurance given to those whose details were not accessed.
