Description

Technetium-99 is a metastable nuclear isomer of technetium-99, a key radioisotope in nuclear medicine and industrial radiography. Its primary value lies in its ideal gamma emission properties and relatively short half-life, making it indispensable for non-invasive diagnostic imaging. This product is essential for manufacturers of radiopharmaceuticals, research institutions, and industrial facilities involved in non-destructive testing and calibration.

Application

• Medical Diagnostics: As the precursor for Technetium-99m generators, used in over 80% of all nuclear medicine procedures for SPECT imaging of the heart, bones, brain, thyroid, lungs, liver, and other organs.
• Radiopharmaceutical Synthesis: Serves as the parent nuclide for the on-site elution of Technetium-99m, which is then used to label various pharmaceutical kits (e.g., MDP, Sestamibi, Tetrofosmin).
• Industrial Radiography: Used as a gamma radiation source for the non-destructive testing (NDT) and inspection of welds, castings, and structural components in aerospace, automotive, and construction.
• Scientific Research: Employed as a tracer in chemical, environmental, and metallurgical research to study corrosion, wear, and material flow processes.
• Calibration Standards: Utilized to calibrate γ-ray spectrometers and other radiation detection equipment in laboratories and regulatory facilities.

Quality Control

Our Technetium-99 is produced and handled under strict quality management systems. Each batch is subjected to rigorous radionuclidic purity testing via gamma spectrometry and half-life verification to ensure compliance with pharmacopeial standards for radiopharmaceutical precursors. A comprehensive Certificate of Analysis (COA) detailing specific activity, radionuclidic purity, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its radioactive nature and specific chemical properties, it must be stored in a designated, shielded area in accordance with all local and international regulations for radioactive materials. Store at controlled room temperature. Handle and dispose of in compliance with ALARA principles and radioactive waste management protocols.
