As part of my AS physics coursework I went on a trip to Queen Elizabeth Hospital. The purpose of this trip was to find out the physics involved in Hospital equipment, which is used on patients. I learnt about three different areas where physics is involved. I learnt how physics is involved in Nuclear Medicine, Radiotherapy and Ultra Sound. I will discuss briefly about how physics is used in Nuclear Medicine and I will discuss in greater detail how physics is involved in Ultra Sound. Nuclear Medicine Nuclear physics involves looking at the nucleus of an atom. It involves injecting a highly radioactive material into the body and allowing it to decay. There are positives and negatives in this because nuclear medicine can be used for diagnosis, which can determine functions of an organ or can for simple therapy. On the other hand though radioactive materials are not good for you and so if diseased tissue comes in contact with you then it can cause problems. Using radioactive sources can kill of tumours though. It travels only shallowly into the body and can kill of all the cancerous cells. The unfortunate thing is that it can also kill of healthy tissue. What Is Ultra Sound? Ultra sound is sound with a frequency of over 20,000 Hz, which is a very high limit of human hearing. So therefore humans have a lower limit of hearing and so cannot hear ultrasound.
