2)To develop the analytical service of JSC “NAC “Kazatomprom” the Institute created the Laboratory of research and analysis of materials (LRAM) at its branch “IHT- Zerde” located at Taukent settlement, Suzaksky district, Southern Kazakhstan.
The main purpose of LRAM is analytical support and improvement of technologies for extraction and processing of natural uranium, R & D in the field of geological exploration, extraction and processing of RM, REM and their associated extraction. LRAM passed the accreditation of the testing laboratory in accordance with the national and international standards at LLP “National Accreditation Center”.
3) Development and implementation of an innovative method for determining the mass concentration of total uranium in human urine by inductively coupled plasma mass spectrometry.
This measurement procedure establishes a mass spectrometric method for determining the mass concentration of total uranium (the sum of the isotopes uranium-235 and uranium-238) of natural or depleted isotopic composition in human urine in the measurement range from 0.3 mcg/dm3 to 50 mcg/dm3.
The measurement procedure is intended for measuring safety indicators when working to ensure the protection of citizens' health. The results of the measurements will be used to assess the professional internal exposure of personnel working with radioactive substances at uranium mining enterprises and hazardous industries.
The area of distribution of MP is within the enterprises of “NAC “Kazatomprom” JSC.
In 2019, the measurement method 572-1910-02-TOO-007-2019 “Determination of the mass concentration of total uranium in human urine by inductively coupled plasma mass spectrometry” was developed. The specified method was registered in the register of the State Measurement System of the Republic of Kazakhstan on December 12, 2019 under the number KZ.06.01.00114-2019 and the Certificate of Metrological Certification No. 90 dated 12.12.2019 was received. The method is an intangible asset of “IHT” LLP. By order of the General Director of “IHT” LLP No. 171 dated 27.12.2019, the specified measurement method was approved and put into effect for use in the structural divisions of “IHT” LLP, in particular in the Laboratory of Research and Analysis of Materials. At the moment, work is being carried out to add the measurement method to the Laboratory’s accreditation.
