  • Method for direct measurement of absorbed dose rate of beta-rays and an instrument therefor
    Patent number: 4156139
    Abstract: A method and an instrument are, herein, disclosed for measuring the absorbed dose rate of beta-rays in sites of the human body. The instrument of this invention consists of a filter, a thin scintillator, a photomultiplier tube, a linear amplifier, a discriminator having a plurality of pulse height selection potentiometers for selectively taking in only pulses of pulse heights above specified upper limit of pulse height discrimination, a shaper for shaping the selected pulses, and a dose rate indicator for counting the shaped pulses.The method and the apparatus of this invention are characterized by making the relationship between the counting rate per fluence rate and the maximum energy of beta-ray equal to the relationship between the absorbed dose rate per fluence rate and the maximum energy of beta-ray, and therefore, the absorbed dose rate can be measured independent of the energy of beta-ray.

  • Method for direct measurement of beta-ray absorbed dose rate and an instrument therefor
    Patent number: 4101769
    Abstract: A method and an instrument are, herein, disclosed for measuring the absorbed dose rate of beta-ray in sites of the human body. The instrument of this invention consists of a thin scintillator, a linear amplifier, a pulse selector having disposed in parallel therein a plurality of pulse height selection mechanisms for selectively setting the lower and upper limits of pulse height discrimination according to an epidermal thickness of human tissue, and a dose rate indicator. The method and the apparatus of this invention are characterized by making the relationship between the counting rate per fluence rate and the maximum energy of beta-ray equal to the relationship between the absorbed dose rate per fluence rate and the maximum energy of beta-ray, and therefore, the absorbed dose rate can be measured independent of the energy of beta-ray.
