• No results found

The assessment of the resulting data is being performed according to SPORO-2002 Para.3.3.

Data on LRW activity are being registered in the protocols and submitted to the chief of the RS division and to the chief engineer of the facility monthly. At the end of the calendar year, a plot of activity variation with time is being made.

Monitoring is being performed using the following strategies:

• MOP. LRW radiometry monitoring;

• MOP. MMR specific activity monitoring in water media.

5.4 Sampling of (atmospheric) precipitation is performed using sedimentation method using collector-tanks with 5-7 day exposition. Monitoring is performed according to the following techniques:

• MOP. Radiometry monitoring of radioactive precipitation.

• MOP. Superficial activity monitoring of man-made radionuclides in atmospheric precipitation.

5.5 Water sampling from open ponds is performed using the portable sampler. Monitoring is implemented according to the following techniques:

• MOP. Monitoring of gross alpha- and beta- activity concentration of water media.

• MOP. Specific activity monitoring of man-made radionuclides in water media.

5.6 Sampling of hydrobionts and of bottom sediments is performed in points of seawater sampling.

Monitoring is performed according to the technique «MOP. Specific activity monitoring of man-made radionuclides in bottom sediments, water plants and periphyton».

5.7 Soil and plant sampling is carried out in autumn. Samples are subjected to physical reduction.

Sample analysis is performed using radiometry and spectrometry equipment. Monitoring is performed according to the following techniques:

• SP. Soil sample preparation for measurement of gross alpha- and beta-activity.

• MOP. Soil superficial contamination monitoring.

• MOP. Specific activity monitoring of man-made radionuclides in soil.

• MOP. Specific activity monitoring of man-made radionuclides in plants.

5.8 Water sampling from the technical water-pipe is performed from the distribution system in the laboratory. The sample analysis is performed by means of the direct method using radiometry and spectrometry equipment. Monitoring is performed according to the following techniques:

• MOP. Monitoring of gross alpha- and beta-activity concentration of water media.

• MOP. Specific activity monitoring of man-made radionuclides in water media.

5.9 Radiation monitoring of HPZ and SA territories is performed using either instrumentation method or smear method throughout controlled indexes in compliance with the following techniques:

• MEP. Measurement of equivalent dose rate in the checkpoint.

• MOP. Soil superficial contamination monitoring.

Radiation monitoring is implemented periodically. Maps are made (updated) annually, in terms of reached radiation protection at the facility.

The examination data are compared with the reference levels. If the results obtained are higher than the reference levels, the chief of laboratory immediately informs the RSD chief, takes actions to ascertain reasons of excess RL and jointly with the RSD chief develops measures for RL normalization.

Under condition of a blanket of snow absence, measurements of contamination with alpha- and beta-active substances are preformed both directly and using the smear method.

Radiometry survey of the site with respect to superficial contamination with alpha- and beta-active substances in autumn-winter season under condition of a blanket of snow presence is performed using the direct measurement method.

The results of monitoring are registered in the appropriate act.

Radiation monitoring of vehicles for the personnel transportation is performed according to the established schedule and accompanied with the relevant act.

6 Presentation, registration and storage of the monitoring results

6.1 The results of radiation situation monitoring can be presented in the following forms:

• electronic databases;

• in a form of a plot on the monitor with indication of the established levels of controlled values (using the personal computer);

• audio alarm of excess established levels (using the personal computer).

6.2 The results of radiation monitoring are recorded in the following registration forms:

• journals;

• radiometry examination acts;

• dose cards;

• in electronic form (using the personal computer).

6.3 The results of all dose monitoring types, as well as data on gross dose accumulated by the personnel

over the whole occupational period are registered and stored in compliance with OSPORB-99 requirements.

6.4 The person on-duty of the RSD records individual occupational doses in the Journal and put in the electronic form. The incurred annual occupational dose is subsequently put in the individual card of the worker.

6.5 Copy of the individual exposure data is transferred to the place of new employment, if a worker changes his (her) place of employment for other institution, where operations are implemented using radiation sources. The original is kept in the initial place of employment. Data on individual doses of attached persons are transferred to the place of their permanent work.

6.6 The results of the environmental monitoring are recorded in the protocol in the following registration forms:

• examination protocols;

• examination acts;

• magnet and optic carriers.

6.7 Volume of registered and stored information is identified by the following tasks:

• statistic accounts for the state control bodies;

• dynamics follow-up of all controlled radiation parameter changes, characterizing radiation conditions;

• registration of environmental contamination levels (as necessary, for example, after an accident).

6.8 Data of examinations being specified by the statistic account requirements, according to OSPORB-99, are stored during 50 years. Moreover, generation of necessary data is taken into account, which must be submitted to ASKRO of Rosatom and EGASKRO of Russia, etc.

6.9 The report about the radiation monitoring laboratory work is submitted to the State sanitary and epidemiological supervision bodies not later than 15 February of the following the accounting year according to form No.18 – Instruction on making report of the industrial sanitary laboratories, sanitary epidemiological units, medical treatment institutions on industrial and sanitary monitoring.
