Founder at ReliScore, Navin Kabra recently shared with the world his insights, on how the nuclear bombs exploded in the 1940s-1960s have permanently contaminated steel production since then. Let’s see how does this impact us now.
Crux of the Matter
The Nuclear Connection
Steel is an alloy of iron with a few tenths of a % of carbon to improve its strength. All steel in the world is divided into 2 categories: Pre-1945 steel and Post-1945 steel.
What Does This Mean?
Nuclear bombs and their tests create radioisotopes that are not found in nature. Eg: Cobalt-60 is a radioactive version of Cobalt-59. They have dispersed in the atmosphere since the 1945 Trinity test.
What Is The 1945 Trinity Test?
Trinity was the code name of the first detonation of a nuclear device. It was conducted by the United States Army as part of the Manhattan Project.
How Is Steel Manufactured?
- Via a blast furnace, with iron ore as the main raw material.
- Via an electric furnace, with sponge iron or scrap iron as main raw materials.
How Is Post-1945 Steel Made?
Manufacturing steel involves atmospheric air or oxygen. So Cobalt-60 gets pulled in too. This means post-1945 steel is contaminated as it has embedded in it such radioisotopes.
Why Worry About This?
The emissions from the contaminated steel would interfere with the measurements of devices like Geiger counters, medical devices that check for radioactive contamination.
What About Pre-1945 steel?
Also called low background steel, it is non-contaminated. That’s why particle physicists look for both steel and lead in sunken shipwrecks for dark matter experiments.
Radioactive Isotopes Test For Forgery
Using radiocarbon dating, counterfeit artworks can also be uncovered using small samples of canvas and paint chips.
- Nuclear warfare strategy is a set of policies that deal with preventing or fighting a nuclear war. The policy of trying to prevent an attack by a nuclear weapon from another country by threatening nuclear retaliation is known as the strategy of nuclear deterrence.
- The Doctrine for Joint Nuclear Operations was a U.S. Department of Defense document publicly discovered in 2005 on the circumstances under which commanders of U.S. forces could request the use of nuclear weapons. The document was a draft being revised to be consistent with the Bush doctrine of preemptive attack.
- Robert Oppenheimer was an American theoretical physicist and professor of physics and is among those who are credited with being the “father of the atomic bomb” for their role in the Manhattan Project, the World War II undertaking that developed the first nuclear weapons.
