Radioactive source personal dose detection device

Abstract

The invention discloses a radioactive source personal dose detection device which comprises a main control module, a radiation detection module, a motion detection module and a ZigBee communication module. The main control module is a single-chip microcomputer, the radiation detection module is a semiconductor detector, and the motion detection module detects position information in real time. The radiation monitoring module and the motion detection module transmit detection results to the main control module, and information is uploaded to a background monitoring center through the ZigBee communication module. According to the invention, an induction coil is used for wireless charging; identity recognition is carried out through NFC communication; an OLED display module displays the radiation dose and the electric quantity, and the screen can be turned on by pressing a key and turned off automatically; and when the dose value exceeds the threshold, an alarm is given in various modes. The detection device can be made into a light, thin and portable card, and is high in integration level; the detection effect is good and the precision is high; and dosage and position information can be transmitted in real time, backtracking and hidden situation checking are facilitated, and the safety of radiation workers is guaranteed.

Description

technical field [0001] The invention relates to a radiation source personal dose detection device. Background technique [0002] In the oil well logging industry, inspectors may be exposed to ionizing radiation, such as X-rays, γ-rays, electrons, neutrons, protons, etc., in daily logging work. Ionizing radiation has strong penetrability and energy, which can cause Alterations in the chemical balance of cells, some of which can lead to cancer, and the release of energy in human tissues, leading to cell death or damage. The relevant state departments have formulated regulations to monitor the personal dose of radiation workers to strengthen the management of radiation diagnosis and treatment work, ensure the quality and safety of medical treatment, and protect the health rights and interests of radiation diagnosis and treatment workers, patients and the public. Therefore, personal dose monitoring of radiation workers Dose monitoring is especially important. At present, the c...

Problems solved by technology

At present, the common personal dose monitors mostly use gas detectors such as GM counter tubes, which have low energy detection accuracy; they are large in size, not easy to carry, and are not connected to the background system, so they cannot report radiation value information and location information in real time.
