  • Page 5 Ionizing radiation is a natural phenomenon permanently existing in the environment. Radiation background of the Earth and the space adversely affects us on the regular basis. We are constantly influenced by natural radioactive materials stored in soil and construction materials of the buildings we live and work in. It also happens that more and more frequently we are exposed to the radioactive influence of specific life activities, for example, certain medical procedures, smoking etc.
  • Page 6 X-ray and gamma radiation is transmitted as energy waves, similar to the transmission of sunlight and sun warmth. X-ray and gamma radiation have similar nature. They differ only in their origin and wavelength. Normally, humans are influenced by X-rays emanated by electronic apparatuses used in hospitals.
  • Page 7 Alpha radiation is a flow of nucleuses of helium. It has small permeability and can be hindered, for example, simply by a piece of paper. Therefore it is not hazardous until radioactive materials emanating alpha particles get into human organism either through open wound, or with food and air. Beta radiation is a flow of electrons.
  • Page 8 However, because people are more often exposed to gamma and beta radiation in everyday life, the majority of radiation monitoring devices measure exactly these kinds of radiation. As a matter of fact, the MKS-05 “TERRA–P” dosimeter- radiometer, designed on the base of the modern professional dosimeter-radiometer MKS-O5 “TERRA”...

  • Page 9: Preface

    Preface This operating manual (hereinafter referred to as the OM) is intended to inform the user about the principles of operation of the MKS-05 “TERRA-P” dosimeter- radiometer and its operation procedure. The OM contains all information necessary for proper use of the dosimeter and full realization of its technical possibilities. The MKS-05 “TERRA-P”...
  • Page 10 The OM contains the following abbreviations and symbols: - ambient dose equivalent; - ambient dose equivalent rate; MODE - on/off button and switch between the corresponding modes of indication (gamma radiation DER, gamma radiation DE, real time (clock) and alarm clock); THRESHOLD - button of threshold levels programming and correction of clock and alarm clock time.
  • Page 11 Note. Ambient dose equivalent (expressed in “Sieverts” (“Sv”)) characterizes the influence of ionizing gamma radiation on the biological object (human), as opposed to exposure dose (expressed in “Roentgens (“R”)”) that characterizes the capacity of gamma radiation to ionize the air. Generally, to make it simple, use the coefficient circa 100 to covert ambient dose equivalent units into exposure dose units: 1.0 μSv ...
