    Stopping Power of Alpha Particles in Some Human Body Tissues Using Density Functional Theory by Wejdan Abd Almonem, Rashid O. Kadhim

    Published 2023-12-01
    “… In this research, the stopping power, range, and stop time of alpha particle (He+2) in lung, bladder, intestine, and ovary human tissues are calculated using density functional theory and Beth's relativistic equation in range of alpha particle energy (0.01-1000 MeV). …”

    Measurement of the insensitive surface layer thickness of a PIN photodiode based on alpha-particle spectrometry by Josemary A. C. Gonçalves, Carmen Cecília Bueno, Fabio de Camargo, Kelly Pascoalino

    Published 2022-12-01
    “… In this work, the insensitive layer thickness of a PIN photodiode (SFH206K - Osram) has been measured by varying the incident angle of a collimated monoenergetic alpha particle beam. This technique is based on the fact that, except for the intrinsic uncertainties of the emission and straggling of alpha particles, their trajectories at different incident angles are distinct, with smaller ones corresponding to the incidence perpendicular to the detector surface. …”
