FIELD: measurement technology. SUBSTANCE: density is measured by method of narrow beam. Source of gamma-quanta is used in form of beam of positron monoenergetic annihilation gamma-quanta. Subject to registration are paired annihilation gamma-quanta emitted in opposite direction, one of which passes through measured substance. EFFECT: higher efficiency. 2 dwg
