PROCESS OF DETERMINATION OF RADIOACTIVITY IN FLOW OF AIR RELEASED FROM ATOMIC OBJECT TO ATMOSPHERE Russian patent published in 1997 - IPC

FIELD: technical physics, determination of level of radioactivity of air masses released from rooms containing nuclear plants to atmosphere. SUBSTANCE: process consists in establishment of dependence between flow of air released to atmosphere and level of its radioactivity, in subsequent probing by radar signal of zone of release of this air to atmosphere in reception of reflected signal, in determination of effective area of scattering of released flow of air by which value of flow rate of air in current discharged from atomic object is found and in determination of level of radioactivity in flow of air by dependence established in advance. EFFECT: improved authenticity and accuracy of process. 1 dwg
