The Effects of Radiation on Cancer There are both negative and positive effects of radiation on cancer. Scientists have discovered that radiation can lessen or increase the chance of obtaining cancer. Radio therapy is a treatment for cancer in which X-rays employ controlled exposure to radiation. Radiation also can save lives. The negative effects on humans are that if over exposed to it‚ it can cause migraines‚ seizures‚ and ultimately‚ death. Firstly‚ external beam radiation therapy used on

The year 2010 was a watershed moment in the field of radiation oncology‚ due to articles written by Walt Bogdanich in the New York Times. These articles critiqued leadership‚ radiation dose‚ and patient safety‚ and accused the community of using unsafe practices (Washington & Leaver‚ 2016). While there had been previous accidents which injured and killed patients during the 1980s‚ those few accidents were attributed to equipment faults‚ as computer equipment was merged with treatment delivery equipment

Brachytherapy (also known as internal radiation therapy) is the use of radioactive ‘seeds’ to help destroy cancerous cells. It is commonly used as a treatment for cervical‚ prostate‚ breast and skin cancer. How long the treatment will take will depend on where the tumor is and how large it is. Brachytherapy works from the inside of the body by placing the radioactive ‘seeds’ into the body next to the tumor. About 4/10 people with cancer have some type of radiation therapy as their treatment. History

Understanding UV radiation The sun sends out different types of radiation – visible light that we see as sunlight‚ infrared radiation felt as heat and UV radiation that we can’t see or feel. Are there different types of radiation in sunlight? Yes. The types of radiation include • visible light‚ which gives us the colours we see‚ • infrared radiation which gives us the warmth we feel‚ and • ultraviolet (UV) radiation. Except in extreme situations‚ neither visible light nor infrared radiation from sunlight
