CATEGORY I
SELF-CONTAINED 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 CATEGORY I CS-137
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.
Model 25. Sample size is
6” diameter x 8” high, volume 3.7liters.
Dose

Rate
with 1,100 Ci. Cs137 source is ~135 R/minute. Dose rate to 100 mm
diameter samples is ~370
R/minute.

12”diameter x 12” high, volume 22 liters. Dose
Rate with 1,900 Ci. Cs137 source is ~ 135 R/minute.
