And large-size y-ray irradiation apparatus, with the source- storage capacity above 500,000 or 1,000,000 curies, is usually
employed for commercial production.
In accordance with their application, the y-ray irradiation
apparatus can be divided into the research-type, production-
type and special-production type.
Research-type Y-ray irradiation apparatus is relatively
small in size, but the requirement for the dosimetric system
and researching means is stricter. In the China-designed and
China constructed y-ray irradiation hot-house of the Agricultural
Science Institute of Heilongjiang Province, a revolving
irradiating platform which is capable of conducting both re-
volution and rotation is installed.
This represents a special
design for ensuring an average and even absorption of dose and
for facilitating dosimetric monitoring.
The production-type irradiation apparatus are mostly required
to have multi-purpose and synthetical treatment functions.
Therefore, the design for the conveying system of the irradiated
products should have satisfactory adaptability and flexibility.
Special-production-type ray irradiation apparatus are
such irradiation apparatus specially used for sterilization of
medical instruments, irradiation of liquid food, etc.
