Dan is CEO of IMI (International Medcom, Inc.). He has been designing and manufacturing innovative radiation detection instruments for over 40 years. Many thousands of these instruments are in use throughout the world in support of public safety, security, nuclear arms control, medical and laboratory safety programs, educational programs, and personal safety applications.

Reflecting on Todayʻs Radiation Safety Environment from the Medcom Lab

To me Geiger Counters have always been about inquiry – what is there around us that we cannot see? How does it affect us? What do they tell us about the world and the universe that we don?t know. It?s all fascinating to me, and I love to get time in the lab or the field to satisfy my curiosity in this arena. But, alas, the hierarchy of human needs puts safety first. And Geiger Counters serve a vital role in the safety arena. We will never know for sure how many lives they have saved or how many unnecessary health problems they have prevented, but the numbers are surely very high. Still, there seems to be a continuous stream of news that hits my phone or desk about unexpected events that put people unnecessarily at risk. Some of these incidents are in the public domain. This report in Scientific American highlights the danger of inhalation of radionuclides, even in secure facilities. Another recent published example involving inhalation is the tunnel collapse at Hanford.

When trained professionals like these get exposed to potentially harmful radiation (and don?t realize they are getting exposed) it reminds me once again that you cannot always count on governments or professionals to give you the information you need to stay healthy.

A friend and colleague of mine, Edouard LaFargue, recently explored an area in France that is frequented by members of the general public, but was once a uranium mining site.  He sent me the picture below, which shows that the area is still contaminated even though maps mark it as uncontaminated. He has written about his visit to that site here.

So I am just putting the word out there to be careful if you are working around radioactive material, and be cautious even if you are not a radiation safety professional working in a regulated environment. This environment has to be suitable for the equipment that you are handling.  Carry proper instrumentation when you think there is the possibility to be exposed to unusual radioactivity, and remember to use it. Remember not all instruments detect alpha and beta radiation. Alpha emitters carry the greatest inhalation risk. All of our Medcom instruments can detect alpha, beta, gamma and x radiation, but our Inspector and Onyx instruments have the greatest sensitivity because they use a large gm pancake detector.

Here in our Labs we are continuously working to improve the tools available to increase radiation safety in the workplace, in communities – and for individual homes and families.  One problem in keeping track of contamination during surveys is lack of geospatial information, and radiation data is not very useful without it. To solve this problem we have added a bluetooth radio option to our popular Inspector Alert. The new Inspector BLE can connect with popular smart phones to record radiation readings with time/date and GPS data. Our IMI Gateway App works on all popular operating systems and smart phones. With these tools, mapping becomes easy and the data becomes useful.

We hope these tools will make the world safer. In any case please remember to be careful out there.

Geiger Counter Evolution – Be Part of the Open Data Revolution

Kickstarter is featuring a new Safecast radiation detector today, July 4, American Independence Day, as part of its Gold program presenting “iconic projects with a twist.” Safecast created something unique in the Geiger Counter World with its Open Source “bGeigie Nano,” which has won much recognition inside and outside Japan, and won a prestigious “Good Design” Award in Tokyo.  The original “Nano” was a kit that required some skill and a soldering iron.   That kit advanced the State of the Art by integrating GPS into the instrument, and by simultaneously rolling out an internet ecosystem to compile and display the data.   Safecast projects have been widely reported on by National Geographic and other respected news outlets.  Safecast is even covered as a model for “surviving our faster future,” in the book “Whiplash” by MIT Media Lab Director, Joi Ito.   While many people have benefitted from kit building workshops, and many more have developed their technical knowledge by participating in the mostly volunteer project, not everyone has the time to build a kit.   The new Raku Nano does not require soldering, so more people can now participate.

Safecast was born during the Fukshima Daiichi reactor melt downs, during a period where reliable and understandable radiation data was largely unavailable.  Safecast is independent and not a political organization, so people of all viewpoints can participate and can see how data is collected and presented.   That in itself is revolutionary, or maybe evolutionary is a better word.  I highly recommend supporting this Safecast Kickstarter Project, which will both advance the radiation detection ecosystem and support a good organization.   There are only seven days left to fund the project, so act fast.

Radiation Hot Spots in Aviation

Interesting article on hot spots at aviation altitudes published by Space Weather.  Anyone who has traveled with a geiger counter on an airplane knows cosmic radiation intensifies at higher altitudes.  This article explores that phenomena.
