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

Nuclear power is “safe”. The UK now has enough radioactive waste to fill the Royal Albert Hall five times over. It is more reliable than other types of power and creates very little emissions. However the cons just outweigh the pros. Where is all this waste meant to go to? The waste will probably end up in the environment harming the earth. It is deemed safe but an accident occurred‚ the consequences would be catastrophic like the Chernobyl disaster. It has been twenty years since the worst nuclear

Is Cell Phone Radiation Really Harmful? With sixty percent of the world’s population using cell phones‚ recent concern has risen from the medical front concerning the harmful effects of cell phone use. All scientific research has concluded that mobile phones do produce RF energy and emit electromagnetic radiation. Studies have also concluded that high levels of RF energy can be harmful to human health. However‚ all scientific studies have not agreed if the levels of RF energy emitted from modern

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

Some studies suggest that there is no evidence that cellphone can cause cancer‚ others are saying that there are credible amount of evidence that the use of cell phone cause health complication including cancer. According to the article “Dangers of today technology” Recent research shows that cellular phones can cause health complication‚ including cancer. “Heavy long exposure to cell phone radiation increases risks for certain type of cancer

Nuclear Energy How could we save our world if we keep on polluting it every second we speak of saving it? Pollution is the biggest problem the earth face‚ if it keeps on going‚ there won’t be an earth to live in. Cleaning up all that pollution in the atmosphere. We need an efficient‚ reliable and quick way to clean up the world’s pollution problem‚ and nuclear energy is the right choice. By using Nuclear energy we could produce less environmental pollution‚ and reduce the speed and amount of
