Effects of Radiation
An Introduction to Radiation and Radioactivity
There are many practical applications of radiation and radioactivity in various fields, including medical, scientific, and industrial activities. In some parts of Japan, people continue to experience environmental radioactivity caused by the nuclear accident at the Fukushima Daiichi Nuclear Power Plant on a daily basis. Understanding the basic science of radiation and radioactivity will form the base of the course, with specific examples from Japan and elsewhere in the world to illustrate concepts.
This course introduces radiochemistry, radiation detection and measurement, and explores radiation’s effect on the human body. You will gain a greater understanding of radioisotopes, radioactive decay, radiations, radiation interaction with matter, and ways to assess radiation exposure. We will explore applications of radiation through various examples including nuclear power generation, diagnostic and therapeutic uses in medicine, and other scientific and industrial uses. Lastly, we will discuss the fate and transport of radioactive cesium in Fukushima in relation to chemical and physical properties of the radionuclide.

What people are saying
barely understandable without reading
Apparently, every single course taught in English by Japanese instructors will be barely understandable without reading the subtitles, due to pronunciation problems; in this particular course this problem is finally addressed: all the videos are dubbed by very clear English, well done!
people getting marked wrong
They also used some of the worst marking strategies for MOOC's such as input text questions that created lots of problems with people getting marked wrong for right answers and peer assessed final exam which is ls nothing more than a random mark with little educational value.
assessed final exam which
content cover several very
The course content cover several very different topics related to radiation: physics, reactor engineering, measurement instruments, environmental recovery, effect on human health.
covered too many topics
Strictly speaking the information itself was good but it covered too many topics with mixed depth, especially where it purports to discuss the impacts of radiation on human health.
little educational value
ls nothing more
waste your time
To their credit they responded to the complaints about input text questions (and hopefully will not make the mistake of using them in the future) and limited the grade impact of peer assessed questions to 10% of the total mark so you could choose not to waste your time with it and still pass.
