Geiger Counters, Radioactive Water and a Wall of Ice

We are generally dedicated to Geiger Counters – the noble tool that lets us see and learn about the invisible realm of radiation that ionizes.

We also post about  radiation detection in general.

We get many questions about radiation detection.  We use this blog as a tool to answer as many of them as we can in one place that we can refer people to.   We try to keep the content understandable by lay people to the best of our abilities, while keeping it also relevant and useful for professional health physics, public safety and security people.

Radiation detection is a big conversation.  There are new technologies to discuss, basic physics for those just entering the arena, and general learning about equipment.

Unfortunately, news about Fukushima Daiichi is troubling, and it is dominating peopleʻs attention these days.  We apologize for diverging from the geiger counter conversation, but it is becoming evident that Daiichi is something we need to be concerned about.  See CNN story.  Itʻs not as bad as some people claim it is, but there are many challenging problems yet  to be overcome.   We wish those responsible for the cleanup good luck, and we hope the workers will get medals, recognition, lifetime medical care, health monitoring, and benefits for their families.  Itʻs a gnarly situation and they are some of the heroes who are risking their personal well being for the rest of us.

Itʻs heartening that the Japanese government is jumping in to play a greater role in managing the emergency, and that outside advisors are being used.   See related Reuters article.  The situation is forcing “outside the box” thinking.   A “Wall of Ice” is being proposed as a way to stabilize the problems with groundwater.   See MIT Technology Review article.

Finally back to Geiger Counters: Japan Post (think the equivalent of US Postal Service) is partnering with nonprofit Safecast to get more granular data into the maps jointly developed with MIT Media Lab and Keio University.  See video (in Japanese).

Letʻs all wish Japan luck getting the Fukushima Daiichi situation under control.  Weʻll try to get back to more articles on geiger counters and radiation detection, including how to do basic testing of water, air, food.
