About the Course

Radiation is all around us - without it we wouldn’t exist. Yet the word has become synonymous with danger, death and disaster. This MOOC will allow the world to see radiation in a new light, to expose its benefits as well as its risks. X-ray radiation, for example, is a scientific and medical discovery that has improved or prolonged billions of lives. Very few of us have had an X-ray at some point in our life, at the Dentist, in a hospital or clinic. Yet few people really understand what X-rays are or where they come from. In this course, we will travel along the spectrum of electromagnetic radiation from unimaginably long to infinitesimally small wavelengths. At each significant point along the way we will stop and consider: What is the wavelength and frequency of this radiation? Is it ionising or not? Who discovered it and how? What are the uses of this radiation and What are the risks associated with it? Through this we hope to clarify a topic that is often confusing and concerning for many....

A very engaging & thought-provoking course providing the insights from atomic structure to Electromagnetic Radiations, how they interact with matter and associated health effects. The course is quite helpful in particular to clear many myths related to the impact of radiation on the human body, while also explaining working of many medical imaging & examination techniques (like MRI, PET, etc.) Overall, a well-presented content in a lucid & entertaining manner, aptly complemented by noteworthy graphics & videos. Thanks to all instructors and contributors. I'd say the course is simple to follow and worthy of binge-watching - One can finish sooner than prescribed duration (I was able to complete it in a single day :)).

and one can finish earlier than prescribed duration (I was able to complete the full course in a single day - like )

This was a good review of the basic physics and science of radiation. It contained some excellent details on medical imaging and the identification of types of imaging as well the risks, uses and justifications for each. Not all lectures were ideal or well organized but were mostly great for entry level or for health care practitioners not dealing directly with medical imaging and radiation therapy or nuclear medicine.
