Quick Revision ( SCIENCE SERIES, Art 2): NUCLEAR TECHNOLOGY, RADIOACTIVITY and Its application Nuclear technology: Nuclear technology is technology that involves the nuclear reaction of atomic nuclei. Among the notable nuclear technologies are Nuclear Reactors, nuclear medicine and nuclear weapons. BASIC CONCEPTS: Nuclear Energy: The energy produced due to changes … Read more
Nuclear reactors A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power Plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), … Read more
Electric discharge in gases Electrical discharge through gases is studied by using a specially designed glass tube commonly called as a discharge tube. It consists of a cylindrical glass tube having a side tube, and two metallic electrodes one at each end. These electrodes can be connected to the respective terminals of a … Read more

It has been determined that the amount of greenhouse gases have decreased by almost half because of the prevalence in the utilization of nuclear power. Nuclear energy has the least effect … Read more
Nuclear physics Atoms in nature generally are electrically neutral, as they have equal numbers of protons in the nucleus and orbiting electrons. However, within the nucleus there are other particles called neutrons, which are electrically neutral but have about the same mass as protons. There are two numbers used to characterize a nucleus: Z, the … Read more
The Silent Epidemic: Diseases Caused by Environmental Degradation The Earth, our home, is facing a multitude of environmental challenges, from climate change to pollution and deforestation. These challenges are not just abstract concepts; they have a direct and devastating impact on human health, leading to a silent epidemic of diseases caused by environmental degradation. This … Read more
The Heat Budget of the Atmosphere: A Balancing Act of Energy The Earth’s atmosphere is a dynamic system, constantly in motion and responding to the influx and outflow of energy. This energy exchange, known as the heat budget, governs the planet’s climate and weather patterns. Understanding the intricate balance of incoming and outgoing radiation is … Read more
