One of the ultimate element of the State radiation protection regulation system and function of the Regulatory Authority in radiation protection (RPC) is creation and management of the National Registry of sources of ionizing radiation. In 1999 the State Register of Sources of Ionizing Radiation and Exposure of Workers (thereinafter – Register) was established in Lithuania.
Due to the need of improvement of public health surveillance system and according to the plan of creation of registries attributed the Ministry of Health, the investment project “The development and installation of the State Register of Sources of Ionizing Radiation and Occupational Exposure in Radiation Protection Centre” was implemented at RPC during 2008 – 2009.
New Register was designed to meet the requirements of reviewed Statute of the Register and and objective was to develop the software for the Register in order to effectively and handily collect, store, organize and analyze data of the Register objects. At same time it was important to warranty adequate protection, credibility and accuracy of the data. In the end of 2009 above mentioned project was successfully completed. Since beginning of 2010 Register is endorsed for exploitation and these results realized:
• new Register software developed in compliance with the requirements for State information systems;
• necessary hardware and software installed;
• links with Residents’ Register and the Register of Legal Persons established;
• faster and more convenient data delivery to the Registry via the Internet realized (since 1 June 2010);
• modern data protection measures developed and implemented.
LEGAL BASIS
Law on Radiation Protection designates the constitutor and manager of State Registers of sources of ionizing radiation and occupational exposure.
The necessity for accountancy and control of sources and doses of workers is indicated in the Order No. 335 of the Minister of Health On the Order of Presentation of Information about Sources of Ionizing Radiation and Data about Radiation Workers to the State Register of Sources of Ionizing Radiation and Exposure of Workers, adopted on 20th July 1999.
Submission procedure of information on export and import of sources is determined by the Order No. 302 of the Minister of Health On Order of Presentation of Information about Nuclear, Radioactive Substances and Other Sources of Ionizing Radiation, Transported through Border of the Republic of Lithuania, adopted on 23 June 1999.
Management of the data and use of it, security and links with other registers in Register are implemented according to the Government resolution No. 460 and resolution No. 651 On the Establishment of the State Register of Radiation Sources and Exposure to Workers and Approval of its Statute modification (adopted on 9th may of 2007).
The order No. V-675 of the Minister of Health, adopted on 24th August 2009 On the Approval of the Procedure of Submission Data about Sources of Ionizing Radiation and Data about Radiation Workers to the State Register of Sources of Ionizing Radiation and Exposure of Workers defines the order of the accountancy and control of sources. This order instructs the licence holder on preparation of the documentation regarding workers involved in activities with sources (starting, finishing work or any change in activities) and submission of it to the Register. Required data must be submitted within 10 working days (
11 attachment).
Lithuanian Hygiene Standard HN 83:2004 “Radiation Protection and Safety of outside Workers” establishes requirements for radiation protection and safety for outside workers, who are sent to other licensees to perform activities with sources in a controlled zone and are subject to exposure, when effective doses can be above 6 mSv.

REGISTER DATA
The Register consists of two parts: in the part of Sources of Ionizing Radiation the data is collected on enterprises, institutions and organizations in Lithuania, that import, export, store, use sealed and unsealed sources, X-ray generators (X-ray tubes), accelerators and data on radioactive waste, transferred for interim storage (disposed), also disused X-ray equipment, accelerators and punctured (destroyed) X-ray tubes. The above mentioned data system allows tracking the movement of all sources in the country from “cradle-to-grave”, also the possibility is provided to conduct supervision and control of the safety and security of sources
Other part of data accumulated in Register is doses of occupational exposure. Data on occupational exposure is accumulated since 1992, data on occupational exposure at Ignalina NPP – since 1983. Monitoring and evaluation of occupational exposure gives information about workplace hazards and helps to find solutions on how to protect people. Purpose of Register of occupational exposure (hereinafter – Register) is to collect, register, treat and systematize, store and give data directed by law, about workers, who work with sources of ionizing radiation, professional irradiance.
The variation of number of occupational doses collected in the Register during 2008–2010 is shown in picture 1.
