Figure 19From: Hybrid monitoring and measurement of concrete shielding activation at the ProtherWal proton therapy centreEvolution of the CI expected at the most activated depth of the South up LAC core (left) and the South down regular concrete core (right). Long- and short-term radioactive nuclides are considered in these results. The irradiation and cooling patterns follow the hypothetical one-week irradiation scenario discussed in the text. For each material, the CI value reached after 20 years of centre operation is represented in black for comparison purposesBack to article page
