Radiation alarm master unit 3 further includes the first display module, and radiation alarm part-unit 4 further includes the second display module,
It is respectively used to show the radiation agent magnitude that the detection module of itself is obtained, operating personnel is prompted to close directional type X ray in time
Source adjusts its power.Simultaneously as the radiation agent magnitude of radiation alarm part-unit 4 can be logical by second communication module and first
Module transfer is believed to radiation alarm master unit 3, and therefore, the first display module of radiation alarm master unit 3 can also show radiation
The radiation agent magnitude of alarm part-unit 4.
The present embodiment legal person x-ray imaging detection radiation alarm system further includes personal radiation dosimeter 5, is worn on work
With industry personnel, for monitoring the personal dose of radiation being subjected in real time and the long-term accumulative dose of radiation being subjected to and accordingly making report
It is alert, operating personnel is prompted to stop or exit x-ray imaging detection operation.
Directional type x-ray source is closed after detection, each detected value and acoustics report shown according to radiation alarm master unit 3
Alert condition（Including radiating the radiation agent magnitude harmony alarm condition of alarm master unit 3 itself detection and alarming from radiation sub
The radiation agent magnitude harmony alarm condition that unit 4 transmits, radiation alarm part-unit 4 detects）, judge whether to need to adjust spoke
It penetrates warning elt 1, radiation alarm master unit 3 and radiates the position of alarm part-unit 4 and whether need to add radiation shield 2.
By above description it is found that the advantageous effect of the utility model embodiment is：The utility model embodiment due to
Radiation warning elt, radiation shield, optical alert and the acoustic alert based on radiation agent magnitude have been used simultaneously, it can be to detection
Staff and Migrant women carry out multi-faceted prompting, avoid that detection staff's self-position is improper, radiographic source technical parameter
It sets improper or does not close radiographic source in time, Migrant women is prevented to be strayed into detection radiation region；Meanwhile testing staff can
The dose of radiation radiated along warning elt is grasped according to radiation alarm master unit and radiation alarm part-unit, and then assesses radiation control
The fixed science of zoning processed.
Above disclosed is only the utility model preferred embodiment, cannot limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claims still belong to the range that the utility model is covered.
