The invention relates to devices for the radiation detection and analysis, in particular to portable alpha particle sensors adapted for the identification and quantification of radioactive decay products - particles. The proposed invention is a battery-powered pulse ionization chamber particle sensor comprising at least one electric battery, at least one switch S, a voltage converter DC/DC, a capacitor C, a processor MCU, a current pulse amplifier A, an ionization chamber K with an electrode of zero potential placed therein. The ionization chamber K is designed with the possibility of placing a source of particles in it. Furthermore at least one electric battery is electrically connected to the voltage converter DC/DC by means of a switch S, the operation of which is controllable by the processor MCU. The voltage converter DC/DC is electrically connected to the capacitor C and the ionization chamber K. The electrode of the ionization chamber K is electrically connected to the processor MCU through the current pulse amplifier A. The processor MCU furthermore is adapted to execute the instructions: (i) count electrical pulses N, which coming from the K electrode of the ionization chamber and which are amplified by the amplifier A; (ii) by means of at least one switch S, controllably periodically electrically connect the supply of electric energy from at least one electric battery to the voltage converter DC/DC and further in the circuit; (iii) determine the voltage value on the capacitor C and, upon reaching the previously set maximum value of the voltage, by means of the switch S, electrically disconnect the supply of electric energy from the electric battery to the voltage converter DC/DC and further in the circuit.
