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

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

MYP Science One World Essay : Microwave Oven Word Count : 1‚325 Imagine what life was like before the microwave oven was created. Time would be wasted in reheating certain foods when using a stove to reheat. As it takes a long time to preheat a stove‚ which is what was used before the microwave oven to reheat food. Using a traditional stove also tends to create a more stressful environment when being used because of the heat that builds up in the area making it uncomfortable. This does not exist

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

Mexicans and the Cosmic Race Some scholars say that the Mexican was invented. The ’Cosmic Race’ thesis has much to do with this. ’Mexican’ is an expansive term that extends far beyond the easily excepted and common definition that it simply exemplifies a person’s nationality. Like most definitions used to identify‚ trying to define a group by utilizing one trademark is to ignore mass parts of a population. In the proposition that Mexicans were ’invented’‚ the Cosmic Race suggests that this is indeed
