Senator Richard Lugar, and admirable leader and statesman who worked effectively on urgent policy issues, has passed at age 87. Senator Lugar worked across party lines and in cooperation with international communities to prevent proliferation of nuclear weapons and technology during the break up of the former Soviet Union. Weapons and materials that could be used to make weapons were spread across 11 time zones and under loose control. At times the nuclear scientists charged with their care were not … Continue Reading →
Inspector Geiger Counter Measuring Radioactivity on a Firefighters Discarded Clothing
Time flies by. It’s already been 32 years since the Spring day in April when things went terribly wrong in a place called Chernobyl. I was a young man at the time. My first company made radiation detectors and did some solar energy projects and research. The winds shifted in Washington DC and solar had grown out of favor. Today the winds have shifted in the Ukraine and the radioactive … Continue Reading →
The big news this week is that Donald Trump and Kim Jon Un will be meeting.
Let’s hope something good comes out of the meeting that will de-escalate the possibility of nuclear conflict.
Analysts are trying to determine if Russia is really deploying a nuclear powered cruise missile.
Today the Nobel Peace Prize is being awarded in Oslo as the possibility of nuclear conflict is in the news again. Itʻs the holiday season, which is supposed to be about peace, reconciliation, brother and sisterhood. Now is not a good time and there is never a good time for nuclear conflict. Even if war is sometimes justified, nuclear war is not normal war. It is not precise, it creates fallout that travels … Continue Reading →
Seventy two years ago today the first nuclear weapon was dropped on human beings. The debate about whether its use was justified continues. The Washington Post asks “Was it Justified or Needless” here.
A few things about nuclear weapons are not really debatable:
- They are not precision weapons. They destroy everything and everyone within a large radius including women and children.
- The effects of radiation
Health effects from exposure to low dose radiation are always difficult to assess. It has long been assumed that there is no “smoking gun” to link a particular health issue to causation when dealing with the random effects of radiation exposure (especially when there are many other environmental and genetic factors to consider). Looking at a single type of health effect that can occur from radiation exposure, Thyroid Cancer (TC), researchers at Penn State University have postulated that Radiation-induced Thyroid … Continue Reading →
Dealing with deep space radiation is going to be one of the many challenges related to future space missions. This article, published in Nature, looks at health data from the Apollo Mission Astronauts. Not a lot of data to work with, but itʻs interesting. Itʻs also covered by Observer.… Continue Reading →
We have a basic intention here to provide links to news and information that is informative and hopefully empowering. It’s not very helpful to get stressful news about dangers that you have no control over. William J. Perry, former Secretary of Defense has produced a video titled “My Nuclear Nightmare DC.” His position is that we need to think about the dangers we are facing so that we can do something about them. We share this video with trepidation, because … Continue Reading →
A deal has been struck to decommission the PG&E reactors at Diablo Canyon. The reactors have been controversial for many years due to the close proximity of seismic fault lines. There has also been increased concern about the coastal location along the “Ring of Fire” since the tsunami generated nuclear emergencies at Fukushima Daiichi.
The deal will replace the power generated … Continue Reading →

Health Effects of ionizing radiation remains a topic that needs serious attention. Do health effects occur in a linear relationship to dose? That is the position of the BEIR Committee of the National Academy of Sciences. Some researchers argue that there could be a beneficial effect to low dose exposure, and others argue against it. Whether the curve is linear or supralinear or superlinear has also been a matter of discussion for years. Others argue that, as with sunlight exposure, … Continue Reading →
Fortunately 2015 was a year with no major nuclear events. Let’s hope the same for 2016 and continue to watch these stories:
- Use of radiation in medical diagnosis and therapies continues to rise and some experts believe US Doctors are not following guidelines.
- Cold War rad workers still struggle for compensation.
- South African Bishops are calling for a referendum on new nuclear power plants.
- Bangladesh has signed a deal with Russia for new nuclear power plants.
- Despite claims and efforts
I get questions periodically from pilots and flight attendants about occupational radiation exposure. It has been known for some time that the exposures received by some flight personnel would require monitoring with dosimeters if they were working in the medical or nuclear industries.
The challenges to determining dose to a person in flight is complex in different ways than dosimetry on the surface of the planet. High altitude radiation includes particles and rays from distant star … Continue Reading →

What to do with spent fuel from reactors is in the news.
Reuters reports on the complex issues related to removing spent fuel from Fukushima Daiichi Unit 4 here.
A lot of news is breaking on Fukushima Daiichi. While many sources point out worst-case scenarios, some of the pictures painted are clearly exaggerated. Even if the worst-case scenario plays out, it will not be the end of life on the planet, as some in the blogosphere have claimed. Humanity has survived the release of large volumes of nuclear radiation into the atmosphere during the days of nuclear weapons testing, and during the Chernobyl event. Still, there is a lot … Continue Reading →
