Q15: A group of radiobiologists asked you to design a shield to irradiate a sample of cell culture with 0.5 MeV beta. The lab has a 7 MeV mono-energetic beta source. The lab also contain 1 mm thick sheets of lucite (pLucite= 1.19 g/cm'). Design the shield as accurately as possible. Discuss the possible improvement in your design caleulations. Range of beta (R in g/cm2) in lucite is approximately; R= 0.334 T48 0 STS4 MeV and R = 0.53 T -0.106 T> 2.5 MeV %3D
