  • Energy Deposition by Light Charged Particles
    Energy deposition by light charged particles Light charged particles • electrons • positrons All forms of ionizing radiation eventually result in a distribution of low-energy electrons. The interactions of light charged particles are of central importance in radiation biology. The large difference in mass between electrons and heavy charged particles has important consequences for interactions. Light charged particles deposit energy through two mechanisms • Collisional losses • Radiative losses hυ high kinetic energy e– (bremsstrahlung) e– (delta ray) hυ (bremsstrahlung) e– (delta ray) Life history of a fast electron 1 Collisional losses • Electrons lose energy via interactions with orbital electrons in the medium. • This leads to excitation of the atom or ionization. • Energy loss via these mechanisms is called “collisional loss”. • Maximum energy transfer occurs in a “head-on” collision between two particles of masses m and M: and can be expressed as 4mME Q = max (M + m) 2 where E is the kinetic energy of the incident particle. With light charged particles, m = M and so Qmax = E. • The electron collides with a particle of identical mass and thus large scattering angles are possible. • This results in a track that is very tortuous instead of the straight path of a heavy charged particle. 2 Radiative Losses: bremsstrahlung A second mechanism of energy loss is possible because of the small mass of the light charged particle (negligible with HCPs). A charged particle undergoing a change in acceleration always emits “radiative” electromagnetic radiation called bremsstrahlung. The larger the change in acceleration, the more energetic the bremsstrahlung photon. For electrons, the bremsstrahlung photons have a continuous energy distribution that ranges downward from a maximum equal to the kinetic energy of the incoming electron.

  • Chapter 2 DOSIMETRIC PRINCIPLES, QUANTITIES and UNITS
    Chapter 2 DOSIMETRIC PRINCIPLES, QUANTITIES AND UNITS J.P. SEUNTJENS Department of Medical Physics, McGill University Health Centre, Montreal, Quebec, Canada W. STRYDOM Department of Medical Physics, Medical University of Southern Africa, Pretoria, South Africa K.R. SHORTT Division of Human Health, International Atomic Energy Agency, Vienna 2.1. INTRODUCTION Radiation measurements and investigations of radiation effects require various specifications of the radiation field at the point of interest. Radiation dosimetry deals with methods for a quantitative determination of energy deposited in a given medium by directly or indirectly ionizing radiations. A number of quantities and units have been defined for describing the radiation beam, and the most commonly used dosimetric quantities and their units are defined below. A simplified discussion of cavity theory, the theory that deals with calculating the response of a dosimeter in a medium, is also given. 2.2. PHOTON FLUENCE AND ENERGY FLUENCE The following quantities are used to describe a monoenergetic ionizing radiation beam: particle fluence, energy fluence, particle fluence rate and energy fluence rate. These quantities are usually used to describe photon beams and may also be used in describing charged particle beams. 45 CHAPTER 2 ● The particle fluence F is the quotient dN by dA, where dN is the number of particles incident on a sphere of cross-sectional area dA: dN F= (2.1) dA The unit of particle fluence is m–2. The use of a sphere of cross-sectional area dA expresses in the simplest manner the fact that one considers an area dA perpendicular to the direction of each particle and hence that particle fluence is independent of the incident angle of the radiation.

Marshall* and Antonio Pagnamenta** •Center for Human Radiobiology, Argonne National Laboratory, Argonne, 111. 60639, USA, **Department of Physics, University of Illinois, Chicago, 111. 60680, USA. Introduction Growing knowledge about the basic mechanisms of interaction of radiation with matter at both the cellular and the molecular levels may now be sufficient to allow us to localize the targets for the initiation of cancer at the level of indi- vidual particle tracks, ionizations, and particular bonds in the DNA molecule. It seems clear that the explanation for the LET-dependence of cancer initiation lies at the molecular level whereas the explanation for the dose-dependence lies at the cellular level. The finding of a simple mechanism that yielded the correct ratios of the cross sections for initiation of cancer by x rays, beta, alpha particles would greatly strengthen our knowledge of RBE and dose-response and would allow us to extrapolate more accurately than we do with the pure linear model from existing data in cell culture, animals, and man to the low doses and low dose rates of our radioactive environment. In the following, it Is assumed that dose rates are low enough no longer to affect incidence rates.

  • THE IMPACT of DELTA-RAYS on SINGLE-EVENT UPSETS in HIGHLY SCALED SOI Srams
    THE IMPACT OF DELTA-RAYS ON SINGLE-EVENT UPSETS IN HIGHLY SCALED SOI SRAMs By Michael Patrick King Thesis Submitted to the Faculty of the Graduate School of Vanderbilt University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Electrical Engineering August, 2011 Nashville, Tennessee Approved: Professor Robert A. Reed Professor Ronald D. Schrimpf i ACKNOWLEDGEMENT The impact and importance that the support of family, friends, and colleagues has brought to this work is immeasurable in value and my ability to adequately express my appreciation in words. It is my personal opinion that the contributions to this work are vast in scope and varying in magnitude; I am quite grateful for each and every person in my life. To my family, who have been very supportive throughout my decision to leave behind my home and pursue a graduate degree. Whenever I felt as though my grip on this situation was slipping, they were there to offer loving words and tough love as the situation merited, appropriate medicines given in the right doses. Thank you for your unwavering faith that I would find my own way. To my grandfather, Edward Gray, who was my greatest teacher. There has never been a better role model for how to live as a respectable man. He taught me that hard work was every bit as important as intelligence. He taught me that it is not what you were born, but what you have it in you to be. He taught me the value of hard work; to never complain and achieve your goals.

    Chapter 4: Interaction of Radiation with Matter 4.2 Interaction of Heavy Charged Particles NPRE 441, Principles of Radiation Protection, Spring 2020 Chapter 4: Interaction of Radiation with Matter – Interaction of Heavy Charged Particles Energy Loss Mechanisms • Heavy charged particles loss energy primarily though the ionization and excitation of atoms. • Heavy charged particles can transfer only a small fraction of its energy in a single collision. Its deflection in collision is almost negligible. Therefore heavy charged particles travel in a almost straight paths in matter, losing energy continuously through a large number of collisions with atomic electrons. • At low velocity, a heavy charged particle may losses a negligible amount of energy in nuclear collisions. It may also pick up free electrons along its path, which reduces it net charge.
