Abstract
Inventia se refera la un circuit electronic pentru selectarea automata a gamei de sensibilitate pentru dozimetre, care se aplica în aparatura dozimetrica pentru masurarea debitului de expunere, sau a dozei absorbite într-un camp de referinta. Circuitul conform inventiei, este constituit dintr-un integrator care, la cresterea ratei impulsurilor date de un detector cu sensibilitatea mare, comuta automat o poarta de intrare pe semnalul dat de un alt detector cu sensibilitate mai mica, iar la scaderea ratei impulsurilor, comuta pe detectorul cu sensibilitate mare, precum si o baza de timp la valori corespunzatoare fiecarui detector si totodata, semnalizeaza schimbarea intervalului de mpsurare, un alt integrator, care la intrarea în regim nelinear a detectorului cu sensibilitate mica, semnalizeaza saturatia acestuia pana la debitul prevazut pentru suprairadiere, un cadentmetru care, printr-un comutator primeste impulsuri de la detectoarele de radiatii, baza de timp alegandu-se astfel ca, printr-un afisor sa apara o valoare numerica corespunzatoare domeniului de liniaritate a detectorului cu sensibilitate mica, un integrator actioneaza un semnalizator de suprairadiere.The invention relates to an electronic circuit for automatic selection of the sensitivity range for dosimeters which is applied in the dosimetry apparatus for measuring the exposure rate or the dose absorbed in a reference field. The circuit according to the invention consists of an integrator which, when increasing the pulse rate of a high sensitivity detector, automatically switches an input gate on the signal from another detector with lower sensitivity, and when the pulse rate decreases, it switches on a high sensitivity detector, and a time base at values corresponding to each detector, and at the same time signaling the change of the measuring interval, another integrator which, at the non-linear input of the low-sensitivity detector, signals its saturation to the flow rate for over- , a cadencemeter which, by means of a switch, receives pulses from the radiation detectors, the basis of time being such that, by means of a display, a numerical value corresponding to the linearity of the detector of low sensitivity occurs, an integrator acts a sign of overdrive.
