T
he growing use of short half life isotopes in PETimaging has creatednew and more stringent requirementsfor timely and safe transport of radioisotopes
from the production site to the point of end use. The need to provide dependable protection against the more penetrating 511 keV radiation has additionally dictated
the use of thicker shielding than needed for
many of the nuclear medical procedures of
the past.While lead has been the predominantshielding material and still enjoys widespread use, many nuclear pharmacies and end usersalike have opted for lead-free shielding materials in view of the recognized toxicity of
lead. An attractive aspect of tungsten-based
shielding is the freedom from materials
accountability concerns related to the use of
lead in returnable shipping containers.In recognition of these needs within thenuclear medicine community, ATI Firth
Sterling has developed a proprietary line of
tungsten heavy alloy vial
shields for PET
isotopes that offer a number of benefits. 1297 County Line Road • Madison, Alabama 35756Phone: 800-221-4273 • Fax: 800-221-1895
