Work Detail

Laboratory, Optical And Precision Equipments (Excl. Glasses) – Purchase Of Whole Body Counting Measuring System. The Subject Of The Public Procurement Is A Whole-Body Counting Gamma Spectrometry Measurement System Suitable For The Qualitative And Quantitative Determination Of Gamma-Radiating Radionuclides In The Human Body. The Measuring System Must Contain The Following Components: - A Shaded Lying Place (Bed For The Person To Be Measured) - Detectors And A Signal Processing Unit (Analyzer), Which Detect The Gamma Radiation Coming From The Person To Be Measured And Transform It Into A Suitable Signal For The Evaluation Unit - Control, Evaluation And Display Unit By Moving It) - Measuring Individual Body Parts And Organs (Lungs, Thyroid Gland, Skull) Of A Lying Person With A Fixed-Position Detector - Changing The Distance Between The Person To Be Measured And The Detector (Both In The Case Of Scanning And Measurement With A Fixed-Position Detector) According To The Body Size Needs Of The Persons To Be Measured. Shading. The Minimum Internal Size Is At Least 200X60x30 Cm The Requirements Regarding The Detectors: - The Measuring System Includes 1 Solid Scintillation (E.G. Nai) Detector And 2 High-Purity Germanium (Hpge) Semiconductor Detectors - The Relative Efficiency Of The Solid Scintillation And Semiconductor Detectors Is At Least 25% - The Semiconductor Detectors Are Cooled With Liquid Nitrogen - The Semiconductor Detectors Are Suitable For High Resolution (Peak Half Value Width: ≤2 Kev) For Gamma Spectrum Recording In The Energy Range ≤50 Kev – ≥2000 Kev - The Detection Limits Expected From Solid Scintillation Detectors In The Case Of A Scan Measurement Of The Whole Body Lasting 8 Minutes: Co-60: ≤250 Bq, Cs-137: ≤250 Bq - The Detection Limits Expected From Semiconductor Detectors Are A Scan Measurement Of The Whole Body Lasting 8 Minutes For: Co-60: ≤500 Bq, Cs-137: ≤500 Bq - Detection Limits Expected From Solid Scintillation Detectors When Measuring The Lungs With A Fixed Position Detector For 8 Minutes: Co-60: ≤200 Bq, Cs-137: ≤250 Bq - Detection Limits Expected From Semiconductor Detectors When Measuring The Lungs With A Fixed Position Detector For 8 Minutes: Co-60: ≤350 Bq, Cs-137: ≤450 Bq - Detection Limits Expected From Solid Scintillation Detectors When Measuring The Thyroid Gland With A Detector In A Fixed Position For 8 Minutes: I-131: ≤150 Bq - Detection Limits Expected From Semiconductor Detectors When Measuring The Thyroid Gland With A Detector In A Fixed Position For 8 Minutes: I-131: ≤200 Bq - A Solid The Shielding Of Scintillation And Semiconductor Detectors Is At Least 10 Cm Thick Lead - In The Event Of A Power Failure, The Analyzer Connected To The Solid Scintillation And Semiconductor Detectors Must Provide Protection Against The One-Step Reconnection Of The High Voltage Connected To The Detectors - The Measuring System Must Have An Uninterruptible Power Supply
