- Page 2 (not an oven). DO NOT open the unit (except for battery replacement).There are no adjustments inside for the DX-1 that can be made by the user, since the unit is calibrated at the factory with special equipment.
- Page 3 Operation The radiation monitor only operates while the push button on the face of the unit is depressed. This feature makes operation very simple and conserves battery power. The unit is designed to be held in the right hand with the thumb over the push button (see Figures 1 and 2).
- Page 4 Gamma radiation and X-rays can penetrate the plastic case with comparative ease. Beta radiation can most efficiently enter the case through the open slots. Although Beta radiation is easily detected, it is difficult to measure accurately. Therefore, when a radioactive object (such as a “Fiesta”...
- Page 5 In addition to the analog display, a special logarithmic scale has been designed into the DX-1/DX-2. At radiation levels that are in excess of the analog scale, the DX-1 will emit beeps at a rate that increases as the radiation level increases above 10mR/hr.
- Page 6 Interpreting Readings Health physics, the field that pertains to radiation and its effects on man, is very complex, and theories and conclusions are constantly being updated as information becomes available. Data from occupational exposure, animal studies, and events like Hiroshima and Nagasaki have fairly well established the maximum safe exposure limits for man.
- Page 7 Correspondingly, the meter readings should be divided by about 5 as compensation. The opposite is true for cosmic rays (easily detected by DX-1/DX-2 in an airplane above 5,000 feet) which have enormous energy — some millions of times more energetic than anything found here on earth.
- Page 8 the positively charged protons that, along with the neutrons, make up the nucleus. Atoms bond together in molecules when one atom gives up or shares an electron with another atom. Chemical reactions utilize this bonding process. In all atoms, the number of electrons (and therefore the number of negative charges) equals the number of protons (positive charges).
- Page 9 The energy released in each decay can be enormous. This decay process is utilized in atomic reactors and bombs. When certain very heavy isotopes of uranium or plutonium (or several other isotopes) decay, they may split apart. This process is called fission.
- Page 10 Scientists believe that the universe was created from a huge mass of sub-atomic particles and energy — the Big Bang Theory. Of the elements and their isotopes that constitute our planet, the vast majority are quite stable, the result of billions of years of nuclear decay.
