The importance of radiation safety to the treatment of malignant disease with radiotherapy The BTEC students need to know how to deal with radiation safely. Effect of x-rays http://en.wikipedia.org/wiki/X-ray#Adverse_effects Diagnostic X-rays (primarily from CT scans due to the large dose used) increase the risk of developmental problems and cancer in those exposed. X rays are […]

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 × […]
Read more "Year 13 BTEC trip to Northwick Park Hospital"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 […]
