Abstract

The invention discloses a direct-reading X and gamma personal dosimeter comprising an X and gamma detection element, a charge sensitive amplifier and a control system. The X and gamma detection element is connected with an input end of the charge sensitive amplifier, a signal output end of the charge sensitive amplifier is connected with a signal input end of the control system, and information of the X and gamma detection element is processed through the control system. The direct-reading X and gamma personal dosimeter is characterized in that the X and gamma detection element is formed by a scintillation detector and a semiconductor detector in a combined mode, and the semiconductor detector simultaneously serves as a photovoltaic conversion component of the scintillation detector. The direct-reading X and gamma personal dosimeter is convenient to carry and sensitive in response, has alarm functions through sound, light, vibration and the like, is suitable for being worn on the trunk of a human body, monitors the individual dose equivalent and the individual dose equivalent rate of X and gamma external irradiation born by a wearer, guarantees that X and gamma radiation amount of the environment surrounding the wearer is within a safe range, and achieves aims.

Description

Technical field: [0001] The invention relates to a radioactivity detection instrument, in particular to a direct-reading X, γ personal dosimeter which is worn on the human body to monitor the personal dose equivalent and personal dose equivalent rate of X and γ radiation external exposure received by the wearer . Background technique: [0002] At present, there are many kinds of X and γ personal dose detection devices on the market, but most of them have poor data readability and low sensitivity; some can only provide alarm function, and the measurement accuracy is not high; some are too large to be convenient carry. [0003] Therefore, there is a special need for a direct-reading X and gamma personal dosimeter that is portable, has an alarm function and has high sensitivity, is convenient for professional workers to wear in potentially dangerous environments, and can provide information about the X and gamma radiation while monitoring X and gamma radiation. Personnel have...
