Cobalt 60 warning skin#
It resembles iron or nickel.īecause it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death.
Co-60 can occur as a powder if the solid sources have been ground or damaged.Ĭo-60 is a hard, gray-blue metal. Co-60 also is a byproduct of nuclear reactor operations, when metal structures, such as steel rods, are exposed to neutron radiation.Ĭo-60 occurs as a solid material and might appear as small metal disks or in a tube, enclosed at both ends, that holds the small disks. Radioactive Co-60 is produced commercially through linear acceleration for use in medicine and industry. Nonradioactive cobalt occurs naturally in various minerals and has long been used as a blue coloring agent for ceramic and glass. Co-60 also is used for food irradiation, a sterilization process. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Irradiation facility allows achieving acceptable levels of microbial disinfestations and also avoiding sprout inhibition and insect growth, facilitating to have quality products.Mode of decay: Beta particles and gamma radiationĬhemical properties: Metallic solid that can become magnetically chargedĬo-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. , microbial growth and insects growth on fruits render the product value to a lower level making hindrance to local farmers to obtain profit and sustain in the local market and even closing pathways for export market. Gamma irradiation is a viable alternative and now it is available at Biyagama.Ĭoncerning the Agricultural products, sprouting of products such as onions, potatoes etc. The production and the use of methyl bromide which is widely used for fumigation of export products including spices, is being phased out and can affect the export trade if a viable alternative is not found for disinfestation of these products. Some of the export products of Sri Lanka such as spices are irradiated in a European country before it is re-exported. Since the establishment of Sri Lanka Gamma Centre, it was possible to fulfill the requirement of surgical gloves manufactured & sterilized within the country for all the government hospitals, saving foreign exchange, making direct impact to the Economy of the country.Īs Irradiation service is readily available, several entrepreneurs initiated manufacturing facilities for Aprons, Urine collection bottles etc.while some are irradiating imported finished products from SLGC and some are in the process of initiating manufacturing facilities for syringes, Gauze, making opportunity for man power utilization & capacity building within the country. This effect is useful in killing bacteria, insects, or other living contaminants which may exist in or on a product.Īpplications of gamma irradiation has a wide spectrum including sterilization of medical products, sterilization of packaging material, cosmetics etc.Microbial disinfestation and insect control in food and medicinal herbs, sprout inhibition, phyto-sanitary treatments (quarantine treatments), mutation breeding, material modification and sterile insect technique for disease control.Įven though Sri Lanka is one of the major glove manufacturers, as the country has natural resource like latex rubber, surgical gloves were imported spending a lot of money to fulfill the requirement of Health sector, as there was no possibility of sterilizing gloves. These photon-induced changes at the molecular level may cause the death of the organism or render the organism incapable of reproduction. In living cells, these disruptions result in damage to the DNA and other cellular structures. High-energy gamma radiation produces electron disruptions (ionization) in any material that it encounters. These photons can create ionization (electron disruptions) throughout a product. High-energy photons are emitted from an isotope source (e.g., Cobalt 60).
