Gamma irradiation tests in different conditions; accurate and tailor- made dosimetric measurements; dosimetric and irradiation certifications; characterization of gamma radiation induced modification. Among them: mutation breeding: gamma radiation induced mutation is used in a number of crops and species to generate broad spectrum of genetic variability, to increase the production of fruits and seeds, a better ability of plants to withstand environmental stresses (e.g. water deficit) and to increase the content of high nutritional values substances in the edible parts of the cultivated plants; food processing: irradiation used as post-harvest treatment to reduce bacterial contamination, destroying disease-causing bacteria and reducing the risk of food borne illnesses, slow spoilage, keep food longer, ensure a high level of safety and quality and reduce wastes; phytosanitary treatment (quarantine) as viable pest control method in fruits and vegetables; insect pest control: the Sterile Insect Technique (SIT) is an environment-friendly method for the eradication of pests involving mass-rearing and pest males sterilization by gamma radiation, resulting in no offspring and a declining pest population
