    This 90-minute Webinar defines the planetary and interplanetary charged particle radiation environment required to appropriately assess the effects of radiation on personnel and electronics. The effects of charged particle radiation are briefly addressed. Equations of motion are presented leading to an understanding of the mechanisms of particle gyration, gyro-frequency, Larmor radius, mirroring, and drift. The trapped radiation, cosmic ray, and solar event environments are then described in detail. Available models for each are presented with references. Simulation results for a variety of situations are presented.


    Learning Objectives

    • Provide a quantitative understanding of the space radiation environment
    • Provide information on the environmental models available
    • With models, mission profile, and radiation transport codes an assessment can be made of the radiation exposure (energy deposited)
    • With the exposure, the required degree of radiation tolerance and shielding can be determined


    Approach Taught

    • Identify the sources of radiation
    • Identify their time and spatial dependencies
    • Identify the available models of the radiation environment
    • Illustrate the uncertainties in the models
    • Identify applicable radiation transport codes to determine effects of shielding and production of secondary radiation
    • Identify the effects of radiation on electronics


    Who Should Attend

    This Webinar is a must for anyone who wants to gain a greater understanding of the Space Radiation Environment and its effects.
