  6. Slide 6: Alpha Tau – Key Investment Highlights

    Alpha Tau – Key Investment Highlights Proprietary Alpha DaRT designed to safely deliver alpha radiation with localized precision in solid tumors, sparing surrounding healthy tissue 1 Broad potential and preclinical evidence supporting evaluation across various solid tumors (skin, pancreas, breast, G

  7. Slide 7: Types of Radioactive Decay

    Types of Radioactive Decay Due to the mass of the alpha particle, in comparison to beta particle, alpha has a low penetration power. This means that the outside layer of the human skin, for example, can block these particles. 7

  8. Slide 8: Mechanism of Action of the Alpha DaRT Technology

    Mechanism of Action of the Alpha DaRT Technology 224Ra Decay Chain Alpha DaRT leverages the innate decay chain of Radium-224 The decay chain of Radium-224 includes four alpha particles Radium-224 has a half-life of ~3.7 days, while the remaining decay chain has a total half-life of approximately 12
