World Radiation Map

GREAT NEWS! THE NEW WORLD RADIATION MAP IS READY! IT IS PC,TABLET AND CELL PHONE READY. UNDER THE MAP ENTER YOUR INFO. YOU CAN RIGHT CLICK AND SIMPLY PLACE THE MARKER IN YOUR LOCATION.(You do not have to be exact) Enter you Average and Maximum CPM or Microseverts, and Type of Meter.

  1. Here are three slides of a Power Point that came with my Geiger Counter. It may be helpful to others:

    Radiation Basics
    Ionizing (fast flying particles or rays) and Non-Ionizing
    (electromagnetic waves)
    Possible ionizing sources include smoke detectors, pottery, rock
    collections, and the sun.
    NORM – Naturally Occurring Radiation. NORM is found in the
    earth, our bodies, the water, the soil, the air and the sun.

    Radiation Dosage
    Exposure
    Dose and Dose Rate
    Time, Distance and Shielding
    Alpha – wont penetrate skin
    Beta – penetrates first layer
    Neutrons and Photons – penetrate just about anything

    Common Units of Measurements

    Roentgen (R) – Unit of radiation exposure

    Radiation Absorbed Dose (RAD) – Absorbed dose divided by
    the time it takes to deliver that dose.

    REM – Roentgen Equivalent for Man
    For practical purposes (Exposure dose only),
    1 Roentgen = 1 RAD = 1 Rem (gamma & x-rays)

    Counts Per Minute (CPM) – Number of counts taken during a
    minutes time

    Microseiverts per hour (µSv/hr) – The sievert (Sv) is the name of
    the international system of unit of dose equivalent.

    mR/hr and µSv/hr are used for Gamma & X-Ray

    CPM(CPS) is used for Alpha & Beta

    Radiation Basics
    Alpha – radioactive particles. Stopped with paper
    Beta – particles and low energy waves. Stopped with aluminum
    foil.
    Gamma – rays that travel at the speed of light. Stopped by thick
    lead or concrete.
    X-Rays – man-made rays. Stopped by thick lead or concrete.

    SI Units and Common Units

    Common Units Currie(Ci) rad rem Roentgen (R)
    SI Units Becqeurel Gray Seivert Coulomb/
