Life, Health and Radiation at Coursera Course details
- 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. Most 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.
