Portable device for ionizing radiation monitoring

Abstract

The invention discloses a portable device for ionizing radiation monitoring. The portable device comprises a shell and a circuit module arranged in the shell, wherein the shell is provided with a power switch and a display unit which are electrically connected with the circuit module; the circuit module comprises a radiation sensor, a data processing circuit, a wireless transmission circuit and apower management circuit for supplying power to the radiation sensor and other circuits; the power switch is used for controlling the on / off of the output of the power management circuit; the radiation sensor is used for detecting the ionizing radiation value in a radiation environment where the portable device is located; the data processing circuit is used for acquiring the ionizing radiation detection result of the radiation sensor, carrying out analog-to-digital conversion on the ionizing radiation detection result and sending a processing result obtained after the conversion; and the dataprocessing circuit is used for sending data to a client through the wireless transmission circuit, or sending the data the display unit in a wired transmission way. The portable device is capable ofmonitoring dose value and other information online in real time, makes an audible and visual alarm when the dose exceeds the standard, and can make an alarm for the loss of a radiation source.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a portable device for ionizing radiation monitoring. Background technique [0002] Ionizing radiation is radiation that can ionize the subject matter, and is formed by directly or indirectly ionizing particles or a mixture of the two. Ionizing radiation has the characteristics of short wavelength, high frequency, and high energy. Therefore, if the protective measures are not appropriate, when the dose of human body exposure exceeds a certain limit, harmful effects can occur. Energy is released, causing cell damage, death, or transformation into cancer cells. Even if the dose of radiation to the human body does not exceed a certain limit, if a certain dose of radiation is scattered over a long period of time, it can cause chronic radiation damage, such as skin damage, hematopoietic disorders, leukopenia, and impaired fertility. Therefore, detecting ionizing radiation...
