1. Physical Properties

- Dimensions:

o Working area width: 1000 - 1500 mm (depending on intended use).

o Depth: 600 - 900 mm.

o Height: 1500 - 2000 mm (external dimensions).

- Material Structure:

o Body: Stainless steel (grade 304 or 316), can be coated for chemical resistance.

o Window: Lead glass (5-10 mm thickness), provides protection against radiation.

o Work surface: Surface resistant to radioactive materials and corrosive chemicals.

2. Radiation Protection

- Lead Coating:

o Body and side panels: 2-10 mm lead thickness may vary according to the radiation level.

o Different parts of the fume cupboard provide effective protection against alpha, beta and gamma radiation.

- Lead Glass:

o High density glass providing over 90% attenuation against gamma radiation.

3. Ventilation and Filtration System

- Air Flow:

o Laminar air flow at a minimum speed of 0.5 m/s.

o By creating negative pressure in the working area, leakage of material is prevented.
