摘要： PROBLEM TO BE SOLVED: To solve the problem that it is necessary for a conventional iodine monitor to discard a cartridge for radioactive iodine collection even when no iodine is collected during use under an environment where no radioactive iodine is contained.SOLUTION: Even if a cartridge A1 prior to purification adsorbs radioactive radon or thoron together with water vapor contained in sample air SA collected in a collection unit B3, the cartridge A1 is purified by blowing dry gas heated in a cartridge discard box G to remove the radioactive radon or thoron. Therefore, the cartridge can be repeatedly recycled later.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor sensor, a radiation detector, and a radiation monitor having high reliability by reducing effect of vibration or static electricity. SOLUTION: Conductive layers 16a, 16b are provided through an insulator 15, oppositely to negative and positive electrodes 12a, 12b of a semiconductor element 11 for detecting a radiation, and a shield case 3 and the conductive layers 16a, 16b are fixed at the same potential of 0V voltage, and thereby a stray capacitance between the shield case 3 and the conductive layers 16a, 16b is reduced. Hereby, since a ground stray capacitance of the semiconductor sensor 1 is scarcely fluctuated, even if the interval between the shield case 3 and the conductive layers 16a, 16b is changed slightly by vibration of the semiconductor sensor 1, the semiconductor sensor 1 having high reliability without a vibration noise can be acquired. Since the radiation detector 10 is constituted by storing the semiconductor sensor 1 and a preamplifier 2 in the shield case 3, influence of an external electromagnetic noise can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable radioactive gas monitor having improved noise resistance. SOLUTION: In the radioactive gas monitor, a semiconductor sensor 21 and a preamplifier 22 are shielded by double electromagnetic shields composed of an inside electromagnetic shield 23 and an outside electromagnetic shield 24, and an air hole 233 is disposed on an inside incoming radiation film 232. Thereby, even if a deflection is formed in an outside incoming radiation film 242, the distance between the inside incoming radiation film 232 and the semiconductor sensor 21 is not changed and the change in the stray capacitance between the distance can be controlled. Therefore the inflow of the noise to the semiconductor sensor 21 caused by the pulsation of a sample gas can be prevented. Further, by one point grounding these double electromagnetic shield together with the outer shield 33 of a composite cable 300 via 0V of a power unit 52 by a grounding line 56 of the measurement part, and by separately grounding a sample container 1 and a shielding body 3 with a grounding line 5 of a detection part, inflow of the external noise via the ground can be prevented.
