X Rays BTEC students also need to know about the production and control of X-rays. http://en.wikipedia.org/wiki/X-ray http://en.wikipedia.org/wiki/Radiography X-ray radiation is a form of electromagnetic radiation (photons). Most X-rays have a wavelength ranging from 0.01 to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 × E16 Hz to 3 × […]

What is radioactivity? The BTEC students need to understand the basics of radioactivity before they investigate how it can be used in medicine. In order to understand what radioactivity is we need to know what an atom looks like. The simplest model is a nucleus consisting of positive protons and negative neutrons with negative electrons […]

Year 13 BTEC Applied Science students went to Northwick Park hospital to see the equipment used for all the different types of scans. This was really interesting and helpful for our assignment because we got an insight into how the equipment works and a real life point of view of how well they work and […]
