Description

31. The air between flat electrodes of the ionization chamber is ionized by X-rays. The current intensity I, flowing through the chamber is 1.2 microamps. The area S of each electrode is 300 cm2, and the distance between them d = 2 cm, the potential difference U = 100 V. Find the concentration of n pairs of ions between the plates when a current is far from saturation. The mobility of positive ions + b = 1,4 cm2 / (V • s) and negative b- = 1,9 cm2 / (V • s). The charge of each ion is equal to the elementary charge.
