The Bench Top Shield for gamma radiation is constructed of 1.375" thick (35 mm) lead acrylic, providing the equivalent of 0.060" (1.5 mm) lead for shielding gamma radiation. Lead acrylic can be used with low energy gamma emitters. Lead acrylic is not recommended for beta emitters. This lightweight, sturdy shield is ideal for use in hoods, on laboratory benches or any “hot” area where local shielding is needed. Side legs give the shield exceptional stability.
