Monitoring of Radiologically Contaminated Scrap Metal Czech experience Milan Hort State Office for Nuclear Safety Czech republic UNECE Group of Experts on Monitoring of Radiologically Contaminated Scrap Metal Geneva, 5-7 April 2004

Group of experts, Geneva, 5-7 April Regulatory infrastructure State Office for Nuclear Safety (SÚJB) The authority and responsibilities of the SÚJB include state supervision of :  nuclear safety  nuclear items, physical protection of nuclear facilities  radiation protection and emergency preparedness of nuclear facilities and workplaces handling ionizing radiation sources

Group of experts, Geneva, 5-7 April Regulatory infrastructure (2)  Act No.18/1997 (Atomic Act), revised by Act No. 13/2002 and implementing decrees:  No. 307/2002 on radiation protection  No. 146/1997 on special professional competency  No. 317/2002 on type approval and transport  No. 319/2002 on radiation monitoring network 

Group of experts, Geneva, 5-7 April Regulatory infrastructure (3) Czech legislation  based on ICRP, IAEA recommendations  fully harmonized with relevant EU legislation and IAEA standards (TS -R-1,...)  implements all relevant international agreements Czech Republic participates in IAEA Illicit Trafficking Database Programme SÚJB represents the governmental “Point of Contact”

Group of experts, Geneva, 5-7 April Regulatory infrastructure (4)  Legal system of authorization, notification, registration, licensing of practices and sources  Legal system of supervision, inspections, enforcement  National system of accounting for nuclear materials, national register of radiation sources  National register of licensees and registrants

Group of experts, Geneva, 5-7 April Monitoring (1) Customs  on border crossing: portal monitors, hand held instruments, rad. pagers, electronic personal dosimeters  in territory: “mobile groups” in each of local directorates (8) hand held instruments, spectrometers

Group of experts, Geneva, 5-7 April Monitoring (2)  Metal processing facilities: portal monitors, hand held instruments, final product measurement - spectrometers  Communal waste processors: portal monitors (2 incinerators, 1 waste dump)

Group of experts, Geneva, 5-7 April Monitoring (3) Role of SÚJB:  Methodological support  Support in training of Customs staff  Supervision in detection and following processes, especially in more complicated cases  Unusual events database  Decision process

Group of experts, Geneva, 5-7 April Response  Procedure for radioactive material seizure - Recommendation issued by SÚJB  Co-operation with the Czech Police, Fire Brigades, Customs Service  Licensed organizations participate on the detection and analyses of captured materials  Seized material disposed or safely stored  Disposal via licensed organizations on state repositories

Group of experts, Geneva, 5-7 April Reporting (1)  2003: 86 seizures: 3 – border crossing 37 – steelworks 46 – incinerators and waste dumps  Border crossing with portal monitor: events monthly only 3 seizures: 1 metal part contaminated with Co-60 2 NORM  1 missing source reported (Cs-137)

Group of experts, Geneva, 5-7 April Reporting (2) - steelworks / waste processors  1 / 1 radionuclide sources (Cs-137)  7 / 0 metal parts contaminated with Co-60  18 / 1 metal parts (tubes with NORM)  3 / 18 small metal parts with natural radionuclides (watch, compass,...)  0 / 9 NORM, chemical agents (Ra-226), raw materials  0 / 14 hygienic material from medical treatment  8 / - returned without investigation  0 / 3 false alarms, driver after medical treatment

Group of experts, Geneva, 5-7 April Experience  Threat of financial loses push steelworks to monitor scrap metal and their production.  Secondary, it causes pressure to scrap metal collectors to monitor scrap metal.  Not enough licensed person for performing the radioactive material (source) localisation, unloading, separation from the load, identification and analysis  Problem of radioactive source from military and defence programs
