State Customs Committee of Russian Federation
Customs control of ferrous and non-ferrous metal scrap
Chief of Customs control of fissionable and radioactive materials of SCC of RF

The threat of ITRM at the border
can be minimized by the
implementation of two tasks:
– To stop the illicit trafficking of fissionable and
radioactive materials across the Russian Federation
border;
– To organize thorough check at Customs clearance of
fissionable and radioactive materials of the
participants of foreign trade activities (export, import,
transit, temporary import) for their identification by
name and quantity declared in the documents.
The following conceptual principles
are used as well for solving these
tasks:
• 1. Radiation monitoring of all individuals, goods, and
vehicles crossing the Russian Federation customs border;
• 2. Priority of radiation safety activities over legal activities
aiming to institute criminal proceedings against law
transgressors;
• 3. Effective control not deteriorating conditions for the
participants of foreign trade activities;
• 4. Minimization of additional personnel and funds allocation;
• 5. Utilization mostly of national technical facilities.

The technical facilities can be listed as
follows:
•
•

•
•
• Detection:
1. Stationary remote automatic equipment for detection of the excess in
natural gamma-neutron background;
2. Portable universal radiometers of alpha-, beta-, gamma-, and neutron
radiation;
• Analysis:
3. Potable gamma-spectrometers for identification of fissionable and
radioactive materials without opening the package;
4. Gamma-spectrometers with high-resolution semiconductor detectors for
movable customs laboratories;
• Personal:
5. Personal dosimeters to provide safety of the personnel;
6. Personal protection means.

Approach of implementation TF
DR NRM
Border - Detection of minimally possible amounts of NRM with the use of gamma and neutron
radiation detectors in accordance with the work technique of check posts.
1. Critical width and height of control zone:
- For transport stationary TF DR NRM – width up to 6 meters, height up to 3.5 meters,
carrier speed up to 15 kilometers per hour.
- For pedestrian TF DR NRM – width up to 1.5 meters, height up to 2 meters, object speed
up to 5 kilometers per hour.
2. Maximum automation of TF DR NRM control process, reduction of human factor
influence on reliability of control.
3. Taking into account the specificity of customs service activities, which is directed to
maximum economic benefits for national interests, minimization of the time of control
with the use of TF DR NRM along with high reliability of control, obligatory recording of
control results, provision and storage of video information about the control object.
- Absence of competent body or specialized services representatives during control with
the use of TF DR NRM.
Possibility to implement TF DR NRM in unfavorable climatic conditions (open sites).
