Decay by Negatron Emission: In this case a neutron is converted to a proton by the ejection of a negatively charged beta (β) particle called a negatron (β-) neutron → proton + negatron To all intents and purposes a negatron is an electron, but the term negatron is preferred, although not always used, since it serves to emphasise the nuclear [...]
Read this article to learn about the interaction of radioactivity with matter. Alpha Particles: Fig. 13.5 illustrates the passage of an alpha-particle through matter. Because alpha-particles (made up of 2 protons and 2 neutrons) are comparatively heavy and doubly charged, they cause a great deal of ionization as they collide with atomic electrons in the material, knocking them out of [...]
Read this article to learn about the precautionary measures with radioisotopes. The greatest practical disadvantages of using radioisotopes are their toxicity; they produce ionizing radiations. When absorbed, radiation causes ionisation and free radicals from that interact with the cell's macromolecules, causing mutation of DNA and hydrolysis of proteins. The toxicity of radiation is dependent not simply on the amount present [...]
