Abstract: PROBLEM TO BE SOLVED: To determine a direction along which radiation comes without requiring a rotary mechanism.
SOLUTION: A detection part 10 comprises three detection units 14, 16, and 18. The detection units 14 and 16 are detection units of a direction dependent type, and their directions are shifted by 90° from one another. In a standardizing part 50, a standardized discrete value is found by dividing a discrete value obtained by the detection unit 14 by a discrete value obtained by the detection unit 18. Likewise, in the standardizing part 50, a standardized discrete value is found by dividing a discrete value obtained by the detection unit 16 by a discrete value obtained by the detection unit 18. A coming direction determining part 54 determines a coming direction by referring to a response table 56 from the standardized two discrete values.

Abstract: PROBLEM TO BE SOLVED: To measure with good precision the radioactivity of a radioactive reagent administered to a subject. SOLUTION: A pre-dose sample is taken from a subject before administration of a radioactive reagent, subsequently the radioactive reagent is administered, and a post-dose sample is taken. The radiation from the pre-dose and post-dose samples is counted at the same time using radiation detectors 2 and 4. Normalization operation parts 30 and 32 normalize the counting values of both samples based on the sample weight obtained weight measuring apparatuses 14 and 16, respectively. The normalized counting value NBG for the pre-dose sample corresponds to the contributing part of background radiation contained in the normalized counting value NS for the post-dose sample. A subtracter 34 removes the influence of background radiation by calculating (NBG-NS) and determines a counting value attributed to the radioactive reagent contained in the post-dose sample. In addition, a reagent concentration operation part 36 calculates the concentration of the radioactive reagent in the samples.

Abstract: PROBLEM TO BE SOLVED: To stabilize the temperature characteristic of an input stage element in an electrometer circuit connected to an ionization chamber. SOLUTION: A JFET element 22 with two built-in circuits is composed of JFETs 18, 20, and a very weak current from the ionization chamber 10 is input into a gate of the JFET 18. Differential amplification is carried out between outputs of the LFETs 18, 20. A cooling element 30 is joined to the JFET element 22 in a close contact condition, and the JFET element 22 is cooled to keep a fixed cooled temperature by a temperature control part 34. Input resistance is increased thereby to be able to stabilize the temperature characteristic.

Abstract: PROBLEM TO BE SOLVED: To remove the cosmic ray component serving as background noise in a body surface monitor. SOLUTION: Multiple plastic scintillator plates A-R are connected to surround all wall faces of a measurement room where a testee is located. Cosmic ray particles such as μ-mesons pass through a device with high energy, i.e., the cosmic ray event basically passes through two scintillators. The radiation from the testee is not counted by multiple radiation detectors. When the cosmetic ray component is to be removed from the counting rate 12 by the plastic scintillator A, the logical sum of detection pulse signals 2 from the detectors other than the scintillator A is generated by an OR circuit 4. An anticoincidence circuit 10 does not count the detection pulse signals 8 of the scintillator A generated concurrently with the pulses of logical sum signals 6, and the counting rate 12 removed with the cosmic ray component is obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a shielding wall of a whole body counter for measuring radiation in the body. SOLUTION: A cooler 44 for cooling a radiation detector 40 is arranged on the outside of a shielding wall 42. The boundary area of shielding space surrounding the shielding wall 42 is thereby reduced, and the weight of the shielding wall 42 is reduced. The radiation detector 40 inside the shielding wall 42, and the cooler 44 outside of the shielding wall 42 are connected by a heat conductor 46 through a communicating path 50. The communicating path 50 is provided in the inner part of a groove of the shielding wall 42 in the state of being bent from the groove so that a radiation detecting part built in the radiation detector 40 is unable to face from the outside opening of the communicating path 50.

Abstract: PROBLEM TO BE SOLVED: To provide a radiation measuring apparatus in which an energy value can be calibrated simply without using a radiation source for calibration. SOLUTION: An environmental radiation is detected by a detection part 10, and the energy spectrum of the environmental radiation is found by a multichannel analyzer 22. A peak detection part 32 investigates a prescribed search range in the energy spectrum, and it detects the photoelectric peak of K which is distributed widely in an environment. In a reference-value storage part 34, the correct energy value of the photoelectric peak of the K is stored as a reference value. In a comparison processing part 33, the channel of the photoelectric peak detected by the peak detection part 32 is compared with the channel of the reference value stored in the reference-value storage part 34. On the basis of a compared result, a voltage or a gain instruction part 35 adjusts a voltage instruction value to a high-voltage power supply 14 or a gain instruction value to a main amplifier 18 in such a way that the channel of the photoelectric peak is brought close to the reference value.

Abstract: PURPOSE: To obtain a dust monitor which can detect a low-concentration artificial nuclide by a method wherein an object window corresponding to γ-ray energy emitted by an object nuclide is set inside a γ-ray energy spectrum, the total sum of γ-ray counting rates of respective channels in it is found and the contribution portion of radon or the like is subtracted. CONSTITUTION: Object windows W1 , W2 in ranges of about 1050 to 1460keV and 730 to 890keV are set with reference to peaks of 1700keV, 1330keV and 810keV of energy values by object nuclides Co, Co in a γ-ray energy spectrum. Since the peak of 609keV by the daughter nuclide of Bi of radon is close to them, about 500 to 670keV is set as a contribution window Wr . Counting rates of the windows W1 , W2 which reflect the amounts of the Co and the Co are measured, the contribution rate of the Bi basedon the counting rate of the window W2 is subtracted, and more precise counting rates can be found regarding the Co and the Co.
