Scientists have shown high precision neutron detector of explosives and narcotics

Five detectors‘ Dvina-1 ", with high accuracy recognition narcotics and explosives will be before the end of summer in St. Petersburg metro.
Supply company will carry out "Neutron Technologies", created on the basis of the Joint Institute for Nuclear Research. According to the developers, the device has no domestic analogues and significantly superior to foreign ones.

Mobile version of the system for the identification of explosives and narcotics

Joint Institute for Nuclear Research (JINR, Dubna) since 1998, work is underway to study the method of labeled neutrons (MCM) to create explosive detectors (BB) and drugs (HB).

For commercialization of the JINR in 2008 was created Ltd. "Dvina" ("detectors for explosives and drugs"), which is a co-founder of JINR.
JINR and LLC "Dvina" presented a joint project to create a series production in the GC detectors "Nanotechnologies". In March 2010, the Supervisory Board of the Civil Code "Nanotechnologies" approved the project for funding.
To be deployed in the city of Dubna manufacture of explosives and narcotics detectors of 100 systems per year. The existing production facilities allow you to put up to 30 detection systems already in 2011

"In contrast to X-ray machines neutron detector is capable to accurately determine not only the presence but also the composition of suspicious substances hidden in baggage," — told RIA Novosti supervisor of Vyacheslav Bystrytsky.

According to him, "Dvina-1" works on the basis of the so-called tagged neutrons. Particles which emits device interact with substances concealed inside baggage. They generate gamma-rays, the spectrum of which can determine the composition of the substance. The detector is able to detect up to 30 to 10 explosives and narcotic substances.

The minimum weight that can be resolved "Dvina-1" — 100 grams. The smaller the substance, the more time consuming device on his identification.

"On average, the work goes from 1 to 10 minutes. And, when the detector is activated, the operator must be at a distance of 6 meters from him. Then the dose of radiation, which he can get is negligible, "- said Bystrytsky.

He said that the new development has an interest in leadership of the Moscow Metro and OAO "Russian Railways". If the "Neutron Technologies" won the tender, such detectors will be in the capital’s subway and railway stations in major countries.

"Dvina-1" was developed in 2008. The supervisory board of state-owned corporation (now JSC) "RUSNANO" in March of 2010, approved the program of mass production of devices in Dubna near Moscow. To implement the project in the same year the company was founded, "Neutron technology." The cost of a single detector is 7.5 million rubles.
