Ac-225 generation process.

Fig. 2

Probability of producing Ac-225 from bombarding RaCl2 with high energy protons inside the cylinder target as a function of proton energy. The target density is 4.9 g/cm3. An isotropic point proton source was placed inside a RaCl2 cylinder with a 3 cm height and varying diameter (thickness) in an air volume.

Fig. 5

Average proton energy generated from neutron beams interacting with iron at several thicknesses.

Fig. 6

Probability of proton production from neutrons incident on nickel at different thicknesses as a function of neutron energy. The target density is 8.9 g/cm3. An isotropic point neutron source was placed inside a RaCl2 cylinder with a 3 cm height and varying diameter (thickness) in an air volume.

Fig. 7

Probability of proton production from neutrons incident on manganese at different thicknesses as a function of neutron energy. The target density is 7.43 g/cm3. An isotropic point neutron source was placed inside a RaCl2 cylinder with a 3 cm height and varying diameter (thickness) in an air volume.

Fig. 8

Probability of proton production from neutrons incident on iron at different thicknesses as a function of neutron energy. The target density is 7.87 g/cm3. An isotropic point neutron source was placed inside an RaCl2 cylinder with a 3 cm height and varying diameter (thickness) in an air volume.

Stages to find the optimum parameters for Ac-225 generation

Simulation
Stage 1: Bombarding RaCl2 target with high energy protons
Steps123
Vary proton energyVary RaCl2 target thicknessFind optimum conditions to produce Ac-225
Stage 2: Bombarding several materials with neutrons to generate high energy protons found in the optimum condition for stage 1
Steps123
Vary neutron energyVary material type and thicknessFind optimum conditions to generate high energy protons
Stage 3: Combining results from stages 1 & 2 to simulate two hollow cylinders: the inner cylinder is a proton-producing target, and the outer cylinder is RaCl2 to produce Ac-225
Steps12
Proton production (n,p)Ac-225 production (p,2n)
