key point 1 of 6
Discovery of radiation
The discovery of radiation is a journey filled with intrigue, challenges, and breakthroughs. It all began when Antoine Henri Becquerel, a French physicist, left uranium salts in a drawer with photographic plates. The plates were unexpectedly exposed, despite the absence of sunlight. This accidental observation led him to hypothesize the existence of unseen particles emitted by uranium, which he termed as ‘radiations’…Read&Listen More

Applications of radiation
Radiation, often perceived as a harmful and dangerous substance, has numerous practical applications. Medical practices, for instance, often rely upon radiation for both diagnosis and treatment of various ailments. X-rays, a form of radiation, can penetrate body tissues, allowing physicians to visualize internal structures without invasive procedures. This application is essential for detecting fractures, examining organs, and identifying abnormalities…Read&Listen More

Radiation’s impact on human health
Radiation’s impact on human health is presented as a complex, multifaceted issue. On one hand, exposure to high levels of radiation can cause a myriad of health problems, including cancer, radiation sickness, and genetic damage. On the other hand, low levels of radiation can, in some instances, prove beneficial to health. This ‘hormesis’ effect posits that small doses of radiation may stimulate the body’s protective systems, thereby reducing the risk of certain diseases…Read&Listen More

Nuclear accidents and radiation
Nuclear accidents are unforeseen incidents that can have widespread and severe effects due to radiation exposure. They can occur spontaneously due to equipment failure, human error or natural disasters such as earthquakes, causing significant damage to the environment and living organisms. Long-lasting contaminants released due to nuclear accidents can linger in the environment, leading to prolonged exposure and harm. The Chernobyl and Fukushima accidents are grim reminders of the profound and long-lasting impact of nuclear accidents, causing substantial human suffering and economic damage…Read&Listen More

Radiation in medical applications
Radiation in medical applications is a powerful tool, profoundly impacting diagnostic and therapeutic practices. This force, invisible and unfelt, has been harnessed to peer into the human body, to visualize bones, organs, and blood vessels, providing real-time insights about our health in the most non-invasive way possible. From simple X-rays, computed tomography (CT) scans, to more complex nuclear medicine imaging techniques, radiation has been pivotal in diagnosing diseases and disorders…Read&Listen More

Radioactivity in everyday life
Radioactivity is a natural and inevitable part of our daily existence. It could be from the food we eat, the air we breathe, or even the houses we live in. Bananas, for instance, contain a naturally occurring isotope, potassium-40, that is radioactive. Similarly, radon gas, a product of uranium decay in soil, can seep into our homes and contribute to the radiation we’re exposed to daily…Read&Listen More
