Description
Technical field
The present invention relates to nuclear radiation detection field, more particularly to a kind of dosimeter with alarm device.
Background technology
People are exploring effective approach by radiation application in production, life and medicine and hygiene fieldses always, while also exist
Actively seek radiation proof technical measures, make every effort to the harm of radiation being preferably minimized.Radiation dose monitoring is radiation proof
Basis and premise, make the natural and people that crowd is illuminated in UNSCEAR's periodic review environment
The source of work radiation, and relevant risk caused by these sources, and periodically report its achievement in research to the United Nations General Assembly.Mesh
Before, the known dosimeter species with alarm device is various, and energy response scope is typically at 30 kiloelectron-volts to 3,000,000 electronics
Volt, according to the difference of tested dose of radiation and the difference of application environment, can select the different types of radiation with alarm device
Dosemeter.According to the difference of selected detector, the dosimeter with alarm device mainly has four types, is based respectively on ionization
Room, sodium iodide crystal, geiger-muller counter and Annual dose.Wherein first three detector turns detected radiation
Change electric current output into, output current is treated to be converted into corresponding dose of radiation；Annual dose is a kind of thermoluminescence material
Material, after being irradiated by ionizing radiation, electronics and hole are produced, wherein some can be captured in metastable by trap
State, as dose of radiation increases, the electronics excited and number of cavities increase are ionized by defect capture, when material is heated
When, electronics return ground state, along be energy release, a portion (thermoluminescence) in the form of visible ray or ultraviolet light
Release, thermoluminescence intensity are directly proportional to integrated radiation dose.
The dosimeter of currently known conventional belt alarm device is to carry out integral dose monitoring to continuous radiation
, the accumulative shortest time is some milliseconds, the main radiation agent for measuring radiation caused by accelerator or the accumulation of natural radiation source
Amount, can not monitor transient radiation dosage in real time.But the research of nuclear medicine shows, the high transient radiation of radiation dose rate causes gene
The possibility of mutation and gene defect is bigger.In recent years, ultra-short pulse laser technology is quickly grown, ultra-short pulse laser and material
Interaction experiment can produce the extremely short transient radiation of pulse, and usual pulse width is several nanoseconds, and accumulated dose is little, but due to arteries and veins
Rush narrower in width so that radiation dose rate is very high, and the infringement to biological tissue is even more serious.It is existing traditional with alarm device
Dosimeter can not be monitored in real time to the short pulse transient radiation dosage of nanosecond scale, and can not real-time display prison
Survey result.
