Description
Technical field
The utility model belongs to the monitoring technique field, specifically is meant a kind of device that is used for the radioactive source monitoring.
Background technology
Radioactive source is meant material that can produce radiation irradiation or the entity of processing with radiomaterial.Can be divided into sealed source and unsealed source by its sealing condition.Sealed source is sealed in the radiomaterial in involucrum or the tight overlayer, and unsealed source is meant the radiomaterial that does not have involucrum.The ray that radioactive source emits has certain energy, and it can destroy cell tissue, and is heavy then dead, the human body of gently then hurting sb.'s feelings.Research shows that the nuclear safety accident mainly occurs in civil area.
The unit of radioactive source is complicated, usable range is wide owing to use, and seriously is short of with the protection knowledge of source unit, and adding managerial confusion is the reason that causes accident to take place repeatedly.Add the radioactive source colorless and odorless, being hidden in invisible characteristics has also increased the probability that accident takes place.
Radioactive source generally all is placed on the shell of a metal, and volume neither be very big, and under normal situation, it seems to be exactly a metal object or pig, looks in case lose not only difficulty, and causes society panic easily.The nuclear accident of China also is the behavior of non-malice property at present, sell such as working as scrap iron, but a lot of innocent persons of this entail dangers to.Owing to leader's dereliction of duty, protection safety management system and liability accidents such as measure is unsound, the staff lacks safety protection knowledge, violation operation have accounted for more than 80%.Accident again with radioactive sources lost and stolen be main.
In view of this, the current radioactive source monitoring product that occurred in the market, most products all have the GPS positioning function; The GSM/GPRS radio communication function; And being aided with video monitoring function, radiation dose monitoring functions etc. are though such monitoring product can satisfy conventional radioactive source monitoring; But can not satisfy the monitoring under the abnormal conditions, as lose, the radioactive source monitoring of situation such as stolen after taking place etc.
The radioactive source watch-dog needs external like lower component: external power source, GSM signal antenna, gps signal antenna, radiation dose detection probe, the first-class parts of video camera; These parts provide various signals for the radioactive source watch-dog, to reach the purpose of radioactive source being carried out effective monitoring.Under normal circumstances, these functions of components can normally be brought into play, and whole radioactive source supervisory system can realize normal monitoring function.If but under abnormal conditions, whole radioactive source supervisory system, perhaps wherein a certain component failure, therefore whole function can be affected even lose efficacy.As: 1, radioactive source watch-dog and radioactive source break away from or since radioactive source be moved, cause and watch-dog between distance greater than the effective monitoring distance, thereby cause monitoring to be lost efficacy; 2, when radioactive source is moved; Because intentional or fault cause a certain parts of watch-dog or all component functions inefficacies, as lose the external power source supply; Or lose outside camera signals; Or lose external radiation dosage monitoring signal, or lose the gps antenna signal, or lose GSM/GPRS aerial signal etc.Particularly when radioactive source was stolen, these external components can be destroyed, thereby caused whole radioactive source supervisory system to lose efficacy.
Because the singularity of radioactive source is with dangerous, radioactive source monitored reliably is necessary.Must guarantee the reliably monitoring under the normal condition, and the reliably monitoring under various abnormal conditions.
