nuclear medicine single ventilation fume hood

nuclear medicine single ventilation fume hood

Quantity:

Ventilation Fume hood is used when experiment dispensing the radioactive drugs and isotopes (for instance, I-131 and Tc-99). It is also called radioactive medicine dispensing cabinet.

 For Radioactive Medicine Dispensing, all sides of the ventilation fume hood should be lead protective treatment. Normally the Pb equivalent:

 

1. Front and Bottom 40mm Pb,

2. Left and Right side 30mmPb,

 

3. Top and Back 20mm Pb ;

 The Ventilation Fume Hood is surrounded and installed with dovetail Lead tiles, excellent protective effect.

 VD-650D Ventilation Fume Hoods outside dimension: 1700mm Length*745mm Width*2200mm H

 

I-131(40-30-20mmPb) Weight: 1200kg.
