The electromagnetic spectrum - Life, Health and Radiation

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.

The course content and duration is well framed. The lectures are very lucid and quiet interesting. Feel happy to be certified by the University of Sydney.,The Course Gives a good ideas about Electromagnetic spectrum and its piratical applications, safe uses.. Thank you for this interesting Topic
Welcome to the MOOC! This week, we will drill down and examine the world of atoms. By first understanding the structure of atoms, we can then look at how radiation interacts with them. In this module, we will also unpack the two kinds of radiation: particulate and electromagnetic. We will then take our first glimpse at the electromagnetic spectrum.
