Cobalt 60 Essay

551 words - 2 pages

Krizia ChamCobalt 60Cobalt 60 is produced artificially by neutron activation of the isotope. Cobalt 59 has 32 neutrons (59-27) and cobalt 60 has 33 neutrons (60-27).Cobalt 60 has many uses in the medicine and the industry world. One of the main reasons Cobalt 60 is used, is medically by the use of gamma rays and beta particles emitted. Co-60 isotopes are to treat conditions such as cancer. Gamma rays are not particles but bursts of energy released after alpha and beta particles have been emitted. The gamma ray is highly penetrating and can be stopped by lead or concrete, and travels at the speed of light. Co-60 is also medically used for radiation therapy for implants and similarly as external source of radiation exposure. Cobalt 60 is mainly used for a therapy name 'Gamma Knife'. Gamma knife is a therapy which allows doctors to treat brain tumours patients because the scan is really precise. Gamma knife is a highly effective and precise instrument that uses radiation of 201 beams to treat the brain. Because Co-60 is very reliable on the Gamma knife therapy, it has been running for almost 60 years. The benefit of gamma knife treatment is that it is safe. Because the radiation falloff is very steep outside the target area, the surrounding brain tissue is spared harmful after effects. With approximately 40 years of clinical research 700,000 patients were treated worldwide, the Gamma knife has along, evidence-based clinical record in treating a variety of indications with fewer risks than open surgery in a single outpatient treatment session without general anaesthesia. The gamma knife is highly effective with 700,000 patients treated. Gamma knife surgery is highly cost effective and generally fully reimbursed by insurance. The cost for Gamma knife surgery is normally half the cost of open surgery, saving both healthcare institution and patient money. The treatment provides quick recovery, allowing the patient to return to their usual activities and lifestyle, and requiring little or no rehab services. Cobalt-60 undergoes...

Benefits and Inherent Risks of the Nuclear Industry

1000 words - 4 pages because so many lives are saved by the radioisotopes. In the food industry there are many benefits and inherent risks. Food irradiation is a method used to make the food safer to eat and have a longer shelf life. The do this by exposing the food to the gamma rays of a radioisotope. The most common isotope for this is cobalt-60. The gamma ray is the most penetrating of all the particles, when the gamma ray passes through the food it destroys

Radium. This essay describes, gives a history of, and gives properties of the element radium.

Since then, it has been replaced by radioisotopes that are more stable and safer to use such as cobalt-60 and caesium-137. Because of the high radioactivity of radium, one of its few special ffeeeeeeeeproperties is that it glows in the dark. It was once used to make the hands on watches illuminate. It was found
