  • Radiometric method for determining concentration of naturally occurring isotopes and device therefor
    Patent number: 4476388
    Abstract: The proposed method essentially consists in that a sample of a substance is placed between two scintillators in immediate contact therewith whereupon said sample is hermetically sealed. Arranged in close proximity to each scintillator is a photomultiplier tube recording ionizing .alpha.- and .beta.-radiation. A selector is utilized to select pulses corresponding to .alpha.- and .beta.-particles, and delayed coincidence circuits of a recording element separate and record .beta.-.alpha. and .alpha.-.alpha. cascade pairs of delayed coincidences of RaC, ThC, and AcA radionuclides. Flows are measured twice at a predetermined time interval to account for emanation build-up tendency and concentration of isotopes of radium is determined from the formula ##EQU1## where q.sub.Ra.sup.A =concentration of a given isotope of radium;.epsilon..sub.A =isotope-of-radium concentration unit sensitivity of measuring equipment;.PHI..sub.1, .PHI..sub.
