<p><P>PROBLEM TO BE SOLVED: To provide a radiation monitor for reducing the effects of electromagnetic induction noise of both of an ionization chamber which generates very small ionization current signals by the incidence of radiation, and a signal converter which converts the very small ionization current signals. <P>SOLUTION: All of the ionization chamber 1, a high voltage cable 2, a current signal cable 3, the signal converter 4, and a composite cable 5 are electromagnetically shielded by a double shield of outer shields (11, 21, 31, 41, and 54) and inner shields (12, 22, 32, 42, 451a, 451b, 451c, 511, and 521). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
