Crimes involving radioactive substances

Crimes involving radioactive substances is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Crimes involving radioactive substances rather than just read about it. In short: This is a list of criminal (or arguably, allegedly, or potentially criminal) acts intentionally involving radioactive substances. Inclusion in this list does not necessarily imply that anyone involved was guilty of a crime.

Key takeaways

  • Crimes involving radioactive substances belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Crimes involving radioactive substances to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Crimes involving radioactive substances from memory before moving on to harder problems.

Reference excerpt

This is a list of criminal (or arguably, allegedly, or potentially criminal) acts intentionally involving radioactive substances. Inclusion in this list does not necessarily imply that anyone involved was guilty of a crime. For accidents or crimes that involved radioactive substances unbeknownst to those involved, see the Nuclear and radiation accidents and incidents.

Murder and attempted murder

The Karlsruhe plutonium affair Johannes M. was convicted of attempting to poison his ex-wife in 2001 with plutonium stolen from WAK (Wiederaufbereitungsanlage Karlsruhe), a small scale reprocessing plant where he worked. He did not steal a large amount of plutonium, only rags used for wiping surfaces and a small amount of liquid waste. At least two people (besides the criminal) were contaminated by the plutonium. Two flats in Landau in the Rhineland-Palatinate were contaminated, and had to be cleaned at a cost of two million euro. Photographs of the case and details of other nuclear crimes have been presented by a worker at the Institute for Transuranium Elements.

The Litvinenko assassination

Alexander Litvinenko died from polonium-210 poisoning in London in 2006. British officials said investigators had concluded the murder of Litvinenko was "a 'state-sponsored' assassination orchestrated by Russian security services." On 20 January 2007 British police announced that they had "identified the man they believe poisoned Alexander Litvinenko," Andrei Lugovoi. On 21 September 2012, a story was posted in various UK newspapers suggesting the existence of an ongoing cover-up by the British Government over the material facts of the case. The report suggests that many aspects of the case may "never see the light of day" due to the significant risk to UK/Russian relations and the implications of the declaration that an act of nuclear terrorism took place on British soil.

Roman Tsepov homicide Roman Tsepov, a politically influential Russian who provided security to Vladimir Putin and others, fell sick on 11 September 2004 after a trip to Moscow, and died on 24 September. A postmortem investigation found a poisoning by an unspecified radioactive material. He had symptoms similar to Aleksandr Litvinenko.

Zheleznodorozhny criminal radiological act An unnamed truck driver was killed by five months of radiation exposure to a 1.3 curies (48 GBq) caesium-137 source (about 15 mg) that had been put into the door of his truck around February 1995. He died of radiation-induced leukemia on 27 April 1997.

Vladimir Kaplun radiation homicide In 1993, director of the Kartontara packing company Vladimir Kaplun was killed by radioactive material (cobalt-60 and/or cesium-137) placed in his chair. He died of radiation sickness after a month of hospitalization. The source of the radiation was found after his death.

Worked examples

Example 1 — a first encounter with Crimes involving radioactive substances

Start with the simplest possible case. Write down what Crimes involving radioactive substances claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Crimes involving radioactive substances before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Crimes involving radioactive substances ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Crimes involving radioactive substances

In research
Crimes involving radioactive substances appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Crimes involving radioactive substances in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Crimes involving radioactive substances is common in secondary-school and first-year university syllabi. It links to neighbouring topics Crimes, Nuclear technology-related lists, Nuclear terrorism, so understanding it makes those chapters shorter.
In everyday life
Look for Crimes involving radioactive substances outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Crimes involving radioactive substances in simple terms?

This is a list of criminal (or arguably, allegedly, or potentially criminal) acts intentionally involving radioactive substances. Inclusion in this list does not necessarily imply that anyone involved was guilty of a crime.

Why does Crimes involving radioactive substances matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Crimes involving radioactive substances?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
