WHAT EVEN ARE GAMMA RAYS? well first off gamma rays have the smallest wavelength being no bigger that an at atomic nuclei. it's wavelength is less than 10(-12)m it also has a frequency of 10(20) hertz , 10 picometer. it also has the most energy of any wave in the electromagnetic spectrum.
WHERE CAN THEY BE FOUND? Gamma rays are produced by the hottest most and most energetic objects in the universe such as neutron stars and pulsars supernova explosion, and around black holes
RADIOTHERAPY This method is one where the radiation attacks the cells of the body killing only cancerous cells. This is due to the fact that healthy cells can repair themselves fairly well after being damaged by gamma where as cancerous cells cannot
THE DANGERS However some found dangers are produced from gamma rays during the process of radiotherapy That if large doses are directed at healthy cells during treatment it can begin to not recover killing them off or create cancer in general
FACTS Nearly 2/3 of all cancer patients will receive radiation therapy during their illness. 60% of patients reveal that there is a benefit of a much quicker recovery while using radiation than not using it.
IN CONCLUSION These treatments don't necessarily cure cancer but treating the problem through methods such as gamma radiation can prevent future diagnosis and have a much quicker recovery to health.
