SELF-CONTAINED CO60 PROCESS IRRADIATOR
Model 484C-P. This unit incorporates twin cavities designed to
irradiate two each 16” diameter x 16” high samples (52 liters each) simultaneously.
Maximum loading is 80,000 Ci Co60, which produces a
dose rate of 1 x 106 R/hr (un-attenuated by sample absorption) to
each cavity. Sample irradiation time
will be determined by absorbed dose requirement and product density.
SELF-CONTAINED CS137 IRRADIATORS FOR BIOLOGICAL AND OHER LOW DOSE RESEARCH,
Mark I SERIES
Mark I Irradiators irradiate samples on turntables adjacent to a
line source of Cs137. This provides high radiation
levels for irradiating cells/tissue
cultures in test tubes/culture vessels ≤ 100 mm diameter and lower dose
rates to large numbers of mice/rats in animal chambers on large turntables at a
greater distance from the Cs137 source in the
same irradiator.
For
fractionated doses attenuators to reduce dose rate to full volume samples up to
a factor of 100 are available. For irradiating small sections of animals, such
as leg/tail tumors, the Model 335 removable collimator system which provides an
adjustable, 1 to 30 mm wide full cavity height field of radiation is available
for Models 68 and 68A. Those parts of the animals not exposed over the slit receive minimal doses of radiation.
The
table below lists dose rates available for animal chambers located on the
turntable position which provides minimum dose variation through the radiation
volume. Cs137 source sizes are those typically used with
each Model. Cs137 sources of greater/smaller Curie levels are
available to meet user dose rate requirements. Dose rates are a linear function
of Curie loadings.
