Abstract
During this search, the polymer poly-aniline hydrochloride (PANI-HCL) was prepared with different weights before and after irradiation in the form of films using the casting method. The films were recorded with the cobalt element(CO60), which sends a gama (1.2) Mev for a period of (72) hours. The structural properties of the (FT-IR) were studied. The results showed that the active groups of the recorded polymer were consistent with the chemical composition and topographic study of the prepared film surfaces. The images showed that the recorded polymer is homogeneous and its color changes after irradiation.
 The electrical properties included the measurement of the hall effect and the continuous electrical conductivity and the behavior of the current and voltages where the results showed that the Hall coefficient of the polymer mixture recorded before and after the irradiation are carriers of the (n-type) and through the measurement of current- voltages show results that the polymer recorded conduct the behavior of ohmic before irradiation and walk Conduction of a semiconductor after irradiation. In addition, the results of electrical conductivity were shown to be less after irradiation.

The electrical properties included the measurement of the hall effect and the continuous electrical conductivity and the behavior of the current and voltages where the results showed that the hall coefficient of the polymer mixture recorded before and after the irradiation are carriers of the (n-type) and through the measurement of current- voltages show results that the polymer recorded conduct the behavior of ohmic before irradiation and walk Conduction of a semiconductor after irradiation
The ratio of the voltage created is divided by the current and the magnetic field product by the element thickness, is called Hall coefficient (RH) which is known as a characteristic of the material from which the conductor is made, as its value depends on the type, number and properties of the charge carriers that constitute the current.When the magnetic field is applied perpendicular to the electric field, it yields a current (I) the transverse (e.m.f), which is called Hall voltage (VH), is set up across the sample
The results showed that the Hall coefficient signal negative and this indicates that the carriers in the polymer n-type before and after irradiation due to the bonds of Π, and the values of the concentration of carriers and traffic increased values after irradiation, the values of resistance and the Hall coefficient and electrical conductivity decreased after irradiation, lead to improved electrical properties of the recorded polymer
Summary
The electrical properties included the measurement of the hall effect and the continuous electrical conductivity and the behavior of the current and voltages where the results showed that the hall coefficient of the polymer mixture recorded before and after the irradiation are carriers of the (n-type) and through the measurement of current- voltages show results that the polymer recorded conduct the behavior of ohmic before irradiation and walk Conduction of a semiconductor after irradiation. 5- Electrical measurements The current-voltages of the poly-aniline hydrochloride polymer were measured before and after irradiation using 616C electrometer Keithly device at room temperature and by measuring current voltages the electrical conductivity was calculated and the behavior of current voltages.
