Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

To develop a convenient and simple low-level alpha contamination monitoring method for large quantities of radioactive wastes, a foil-type electret dosimeter was examined. For the electret material, fluoride polymer was used, and the polymer foils were charged and polarized by applying a high voltage in air while heating at ∼150°C. The surface charge density of the electret foil before and after irradiation was measured by converting to a piezoelectret signal through use of a polyvinylidene fluoride. In the experiments, using a 2.5 kV/mm electric field in electret foils, an electron avalanche effect was produced, and surface charge decay was multiplied. The maximum multiplication factor obtained was ∼200. The detection limit of alpha surface contamination was confirmed as 10−6 μCi/cm2 (3.7 × 102 Bq/m2) for a 5-h irradiation time.
