The NEA mentoring workshops are in line with the initiatives being undertaken by countries around the world to ensure that expertise is maintained in highly technical areas such as nuclear safety, radiological protection and other critical disciplines. Capacity-building efforts focusing on science, technology, engineering and mathematics (STEM) fields need to be sustained and reinforced – particularly those aimed at young women, who are significantly under-represented in many areas. It is in this spirit that the NEA partnered with Japan’s National Institutes for Quantum and Radiological Science and Technology (QST) in 2017 to organise its first International Mentoring Workshop in Science and Engineering, on 25-26 July 2017 in Chiba, Japan. The success of this first workshop has led to the organisation of two additional workshops in 2018, both of which are introduced in this brochure – one in Tokyo, Japan, and the other in Ávila, Spain. These workshops are a clear manifestation of the NEA’s commitment to maintaining, and further strengthening, its momentum in encouraging a future generation of female leaders in science and engineering fields.
