In recent two thirty years, the X-ray exposure time has been significantly reduced and the possibility of radiation damage has been reduced due to the improvement of X-ray equipment, the use of high kilovolt technology, image enhancement technology, high-speed intensifying screen and fast X-ray sensitive film. But still can not fall off with ease, and especially attention should be paid to pregnant women, children and workers who are exposed to rays for a long time. In recent years, interventional radiology has been more and more developed, and the problem of radiation protection should be noted.
And to the radiation protection detection outside all kinds of radiation equipment computer lab, meet the accurate position that academician personnel can't confirm six outer faces of computer lab always in the testing process, when this computer lab shielding protection facility effect is fine, check out test set can't measure at all whether ray spills, when the mistake appears in the testing position and computer lab shielding protection is unqualified, will directly influence public's personal safety.
The radiation protection detection equipment performs stationing monitoring at detection point positions according to information provided by field personnel, and the field personnel of most medical institutions cannot give accurate position information. For example, outpatient department and clinic are rented temporarily, the construction of large hospitals cannot provide basic construction drawings for a long time, and the staff is new staff. These all contribute to uncertainty in the monitoring results.
Therefore, there is a need in the art for a new solution to solve this problem.

Detailed Description
As shown in the figure, the radiation protection device with the monitoring point positioning function comprises a high-frequency microwave signal emitter 1 and a high-frequency microwave signal detection display 2, wherein the high-frequency microwave signal emitter 1 is arranged beside a radioactive source or radioactive equipment in a shielding body, and a main chip adopted by the high-frequency microwave signal emitter 1 is TF-M94 VO; a signal detector 201 and a current signal converter 202 are arranged in the high-frequency microwave signal detection display 2, and a display screen is arranged on the high-frequency microwave signal detection display 2; the signal detector 201 detects the signal intensity emitted by the high-frequency microwave signal emitter 1, and the main chip adopted by the signal detector 201 is RDJF 41868; the current signal converter 202 is a semiconductor repeater, and the current signal converter 202 converts the pulse signal sent by the signal detector 201 into a current signal; the display screen displays the current value converted from the detected signal intensity value.
The signal detector 201 includes a gas ionization detector and a scintillation detector.
At present, gas ionization detectors for monitoring X-ray and gamma-ray radiation field doses in China are mainly high-voltage ionization chamber type patrol detectors, such as 451B type and 451P type patrol detectors, 9DP P type patrol detectors and the like; 190N type neutron surveying instrument, FH752 type neutron surveying instrument and the like for neutron radiation dose measurement.
Scintillation detectors for X-ray and gamma radiation field dosimetry are mainly sodium iodide, such as NalTI and plastic scintillators, such as FD-3013B gamma-radiometers using NalTI, 6150AD series using plastic scintillators, AT 1123X-gamma dosimeters, etc.
Example (b):
fig. 3 shows a CT machine room of an outpatient department of orthopedics, because the outpatient department is temporarily leased, a responsible person on site cannot determine the position outside the west wall, if there is no positioning device of the product, the west wall outside the shielding body is a detection area, which is divided into an area 1 and an area 2, and the actual detection area is the area 1.
The position outside the west wall is determined by the radiation protection equipment with the monitoring point positioning function. Firstly, a high-frequency microwave signal emitter 1 is placed on a CT machine, the emission center is aligned with the center of a west-side wall body, the opening is carried out, the total length of the wall body is measured, then a detector holds a high-frequency microwave signal detection display 2 to the outside of a shielding body in the corresponding direction, and signals are received. The high-frequency microwave signal passes through the shielding body where the radioactive source and the radioactive equipment are located, the signal detector 201 receives and detects the intensity of the high-frequency microwave signal outside the shielding body, and the signal is converted into a current value through the current signal converter 202 to be displayed on the display screen. The position with the highest current value is the central position of the wall body to be measured. And finally, the length of the wall body outside the shielding body is determined, the detection area is determined, and the detection data is accurately collected, so that the accurate positions of the radioactive source and the radioactive equipment are determined, and the certainty of the detection result is improved.
