The board of the Nuclear Physics Division (NPD) of the European Physical Society (EPS) calls for nominations for the 2020 edition of the IBA prize for Applied Nuclear Science and Nuclear Methods and Nuclear Researches in Medicine. Every two-three years the NPD board awards the IBA prize, which is sponsored by the IBA company (https://iba-worldwide.com/), to one or more individuals who provided outstanding contributions to applied nuclear physics and/or nuclear medicine.
