In comparison with the increasingly advanced technology of electronic detection devices, it still ranks first on the “podium”. Due to its special abilities the dog is a great support in the fight against terrorism, where the early detection of explosives plays a key role in security. In the training process of a dog for the detection of explosives in Polish uniformed services genuine explosives samples are used. However, international studies have shown that this approach does not give 100% guarantee of HE detection by a dog. In addition, the use of classic HE samples in training involves a risk associated to the safety of both the operator and the dog and is burdened by law enforcement restrictions related to storage, use and transportation. An innovative solution developed during the implementation of the subject “Reference set of explosives samples for training and validation of service dogs” allows for more flexibility while handling the sample, increases the safety of use and provides a better detection of the explosive by the dog.\u0000\u0000","PeriodicalId":439139,"journal":{"name":"PROBLEMY TECHNIKI UZBROJENIA","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114725194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
