    The ports there are two ports on the left side of the digilert 100. The calibration input port (2) is used for calibrating electronically using a pulse generator. For more information, see "calibrating electronically" in chapter 5. The output port (3) below the calibration input port allows you to i...

    When the mode switch is set to mr/hr or cpm, the numeric display is updated every three seconds. At low count rates, significant changes in the radiation level displayed can take up to one minute to stabilize. See "operating ranges and response times" in this chapter for more information. Cpm (or cp...

    To take a timed count, follow these steps: 1. With the digilert 100 operating, set the mode switch to total. The display shows set, the hourglass, and the most recent timing period used. The first time you use the timer, the setting is 00:01, which means one minute. 2. Use the + and - buttons to set...

    Readings. Ionizing radiation ionizing radiation is radiation that changes the structure of individual atoms by ionizing them. The ions produced in turn ionize more atoms. Substances that produce ionizing radiation are called radioactive. Radioactivity is a natural phenomenon. Nuclear reactions take ...

    18 an element may have several forms, or isotopes. A radioactive form of an element is called a radioisotope or radionuclide. Each radionuclude has a half- life, which is the time required for half of a quantity of the material to decay. Measuring radiation alpha, beta, gamma, and x-rays ionize mate...

    A sievert is the standard international measurement of dose. One sievert is equivalent to one hundred rems. A microsievert ( sv) is one millionth of a sievert. A curie is the amount of radioactive material that decays at the rate of 37 billion disintegrations per second, approximately the decay rate...
