Keep reading to learn about high-energy ionizing radiation. Radium Girls In the 1920s, a watch company used the newly discovered substance radium to make its watches glow in the dark. Thousands of girls went to work in the watch factory to do the painstaking painting by hand. To make a ...
Radiation sicknessis an umbrella term for the damage caused by a large acute dose of radiation. In fact, the technical term for radiation sickness isacute radiation syndrome. You might also hear it referred to asradiation poisoning. While both acute short-term radiation exposure and long-term ra...
radiation, low-levelradiobiologyrisk analysisThe fear of radiation has been present almost since the discovery of radiation, but has intensified since the "dawn of the atomic age" over 75 y ago. This fear has often served as an impediment to the safe and beneficial uses of radiation and ...
How Satellites Work "Man must rise above the Earth -- to the top of the atmosphere and beyond -- for only thus will he fully understand the world in which he lives." Socrates made this observation centuries before humans successfully placed an object in Earth's orbit. And yet the Greek ...
This characteristic makes case series a relatively efficient and cost-effective approach because it does not use randomization or comparison groups. However, despite being one of the most representative large databases of tumors in North America, SEER-based case-series investigations are uncommon. The ...
Third, progress in this field has huge leverage on enhanced sustainability of industrialized societies since it eliminates the need to replace what does not need to be scrapped, a key aspect when enhancing product and infrastructure longevity. Therefore, advancing corrosion protection beyond transient ...
That radiation can cause genetic mutation in living organisms was discovered by the US geneticist Hermann Muller (1890–1967). In 1927 he published a paper in Science (66 84) entitled “Artificial Transmutation of the Gene”, his title ambitiously and audaciously invoking the artificial transmutation...

In the early days of X-ray science, a lot of doctors would expose patients and themselves to the beams for long periods of time. Eventually, doctors and patients started developing radiation sickness, and the medical community knew something was wrong. The problem is that X-rays are a form...
