| essay on radiation in medicine help please?
im writing an essay and the topic is 'radiation - a vital part of modern medicine', so ive split it up into two categories - radiation therapy and radiology.
in radiology ive talked about the three different types of imaging - CT, MRI and ultrasound but MRI doesn't use radiation, it uses magnetic and radio waves. so should i include it in my essay even though it doesn't use radiation??
and also shoudl i use ultrasound because it uses sound waves?
