              What is cobalt 60? How to detect cobalt 60?

              2012/12/3 17:06:19 (Views: 12/12/2012 17:06:19)

              Cobalt-60 (60Co) is one of the radioactive isotopes of the metallic element cobalt, with a half-life of 5.27 years. It emits high-speed electrons with energy up to 315 keV through nickel decay into nickel-60, and simultaneously emits two gamma rays with energy of 1.17 and 1.33 MeV, respectively.
              Cobalt-60 has radiation, which affects human hair loss, severely damages the cellular tissues in human blood, causes less white blood cells, causes anemia, leukemia (that is, blood cancer), and even more serious death.
              Cobalt 60 is the raw material of the legendary doomsday bomb. It is said that it can be detonated with high voltage electricity. Because it is easy to obtain, it can easily be made into a 10 billion-ton nuclear bomb, and the pollutants can kill all the higher organisms on the planet. Because of its weird way of detonation, the plane cannot be thrown, so it can only be a revenge weapon. A local explosion can guarantee that the nuclear war enemy is destroyed, so all anti-missile weapons are invalid. This is one of the reasons that the Cold War never triggered a nuclear war. However, because the killing period of nuclear pollutants is only about 50 years, some people are building underground fortresses that can hide for 50 years in order to avoid the nuclear punishment imposed by the other party after the nuclear war.
              The radiation sterilization technology using cobalt 60, a radioactive element, was once popular in the food industry. Although this technology has a good bactericidal effect, if the radiation exposure is not well grasped, it will change the molecular structure of the food, which will lead to the physiological safety of the consumer and induce diseases such as cancer. At present, this technology has gradually been replaced by other technologies such as instant high temperature sterilization. Both Western Europe and Japan have banned imports of irradiated food.

              REN500A Intelligent х, γ Radiometer (Cobalt 60 Detector)
              The REN500A intelligent х and γ radiometer uses a highly sensitive scintillation crystal as a detector, which has a fast response speed. Compared with similar domestic instruments, the instrument has a wider range of dose rate measurement. The instrument has a very good measurement effect on the gamma rays produced by the decay of cobalt-60, and can very quickly and accurately measure the high-energy gamma rays emitted by trace cobalt-60 in metal products such as waste steel and metal. It is a sharp tool for measuring and discovering cobalt-60. This instrument has been widely used in the detection of trace cobalt-60 content in products such as foundry enterprises, iron and steel enterprises, waste metal recycling enterprises and machinery processing equipment export equipment. It is the equipment recommended by the environmental protection bureaus, commodity inspection bureaus, import and export inspection and quarantine bureaus, and public security bureaus to detect cobalt-60.
