The Radiation Center is equipped with a Gammacell 60 Co gamma irradiator which is capable of delivering high doses of gamma radiation to a wide variety of materials. The irradiator is used by researchers wishing to perform mutation and other biological effects studies; studies in the area of radiation chemistry; radiation dosimeter testing; sterilization of food materials, soils, sediments.

ECOLOGY OF THE FIELD IRRADIATOR-GAMMA AREA PRE-IRRADIATION STUDIES II. BOTANICAL METHODS AND VEGETATION SAMPLING PROCEDURES by Janet R. Dugle and Denis H. Thibault ABSTRACT The botanical field methods to be followed in the Field Irradiator - Gamma area (FIG) are described, with the major method involving the use of sampling quadrats- Because.

The Field-Irradiator Gamma (FIG) experiment chronically irradiated a section of the Canadian boreal forest over a period of 14 years.

Forest trees were affected at dose rates > gGyh −1, but a herbaceous plant community thrived at dose rates up to 65 mGyh −ation resulted in the establishment of four zones of vegetation: a herbaceous community, a shrub community, a narrow Cited by: R.

The use of gamma irradiation as a method of disinfesting stored foods, including cereal grains and legumes, has opened a new field for irradiation application in which considerable work has been done (Urbain ).

A precise understanding of possible aging effects of detector materials and gases is of extreme importance. To cope with these challenging requirements, a new Gamma Irradiation Facility (GIF++) was designed and built at the CERN SPS North Area as successor of the Gamma Irradiation Facility (GIF) during the Long Shutdown 1 (LS1) by: The IAEA document entitled "Guidelines for Industrial Radiation Sterilization of Disposable Medical Products - Co Gamma Irradiation", as on the earlier occasions with its predecessor Recommended Code of Practice documents, is aimed at providing necessary guidance on standards and criteria.

Not only does Nordion provide Cobalt to companies in the medical device industry, food industry and other industries for innovative applications for sterilization and irradiation of products, we also manufacture irradiation systems.

The new GIF++ facility has been operational since spring. Radiation is present in the environment from both natural and anthropogenic sources. Civilian use of nuclear materials results in chronic releases of low levels of radiation to the environment, particularly from the nuclear fuel cycle, i.e., the mining and milling of uranium ore to the operation of nuclear power plants, the reprocessing of spent nuclear fuel and nuclear waste disposal.The Field Irradiator-Gamma facility in Pinawa, Manitoba, contains jack pine that have been irradiated longer and at lower dose rates than previously reported.
