Description of Radiation Shielding Fume Hood

Radiation Shielding Fume Hoods are a large radiation shielding workstation used for packing radionuclides. Radiation Shielding Fume Hood is usually made of stainless steel lined with lead shielding and TIG seamless welding technology. Radiation Shielding Fume Hood has the advantages of easy operation, high radiation shielding level, low drug exposure, and long service life. Radiation Shielding Fume Hoods are used for dispensing radionuclides such as iodine-131, mainly to shield harmful radiation emitted by the nuclides in the process of dispensing drugs, and emit radioactive pollution particles in the dispensing cabinet, and then discharge them to the outdoor air.

Features of Radiation Shielding Fume Hood

Double protection: Lead or tungsten alloy housing + negative pressure laminar airflow shields gamma and X-rays, and prevents the escape of radioactive aerosols.

High visibility: Lead glass window with a lead equivalent of ≥5 mm Pb provides both radiation protection and clear observation of operations.

Three-stage filtration: HEPA + activated carbon + potassium iodide-impregnated filter, with a filtration efficiency of ≥99.99%. Exhaust meets GBZ 120 requirements.

Intelligent monitoring: Real-time display of face velocity, negative pressure, and dose rate. Automatic alarm and lock of the transfer door if thresholds are exceeded.

Applications of Radiation Shielding Fume Hood

• Nuclear Medicine: PET/CT and SPECT departments package radiopharmaceuticals such as 18F-FDG, 99mTc, and 131I.

• Research: Radioactive tracer experiments and pre-processing for small animal in vivo imaging.

• Industry: Calibration and maintenance of radioactive sources, and waste sampling and analysis.
