And in the aftermath of the March 2011 earthquake and tsunami that struck Japan, a nuclear crisis raised fears about radiation and questions about the safety of nuclear power.
Nuclear radiation can be both extremely beneficial and extremely dangerous. X-ray machines, some types of sterilization equipment and nuclear power plants all use nuclear radiation -- but so do nuclear weapons.
Nuclear materials (that is, substances that emit nuclear radiation) are fairly common and have found their way into our normal vocabularies in many different ways. In this article, we will look at nuclear radiation so that you can understand exactly what it is and how it affects your life on a daily basis.
You have probably heard (and used) many of the following terms: All of these terms are related by the fact that they all have something to do with nuclear elements, either natural or man-made.
Until recently, Carbon-14 dating was never used to test dinosaur bones, as the analysis is only reliable up to 55,000 years.
Radiocarbon dating has long been used to reveal the age of organic materials — from ancient bones to wooden artefacts.
Radiocarbon dating is one such type of radiometric dating.
The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.
Triceratops, a name meaning “three-horned face”, is a genus of herbivorous ceratopsid dinosaur that is said to have first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America, and became extinct in the Cretaceous–Paleogene extinction event 66 million years ago.
However, scientists from the Paleochronology Group, who perform research relating to “anomalies of science”, maintain that dinosaurs did not die out millions of years ago and that there is substantial evidence that they were still alive as recently as 23,000 years ago.
In Tom Clancy's book "The Hunt for Red October," a Russian submarine has a nuclear reactor accident with radiation leakage that forces the crew to abandon ship.
At Three Mile Island and Chernobyl, nuclear power plants released radioactive substances into the atmosphere during nuclear accidents.
