Properties of Alpha (α), Beta (β), and Gamma (γ) Radiations

December 5, 2023 by DeepakRajput

1. Nature Alpha (α): Consists of helium nuclei (2 protons and two neutrons). Beta (β): Involves high-energy electrons (β⁻) or positrons (β⁺) emitted from the nucleus during a process of neutron-proton conversion. Gamma (γ): Electromagnetic radiation similar to X-rays but with higher energy. 2. Charge Alpha (α): Positively charged. Beta (β): Negatively charged (β⁻) or … Read more

Measurement of radioactivity

December 5, 2023 by DeepakRajput

Radioactivity measurement involves quantifying the amount of radioactive material and the intensity of radiation emitted. Various instruments and techniques are used for this purpose. Here are some commonly used methods for measuring radioactivity: 1. Geiger-Muller Counters Principle: Geiger-Muller counters detect ionizing radiation by counting the number of electrical pulses produced when ionizing particles pass through … Read more

Radiopharmaceuticals- Radioactivity

December 5, 2023 by DeepakRajput

Radiopharmaceuticals are pharmaceutical formulations containing radionuclides (radioactive isotopes) that emit gamma rays or positrons. Nuclear medicine designs these compounds to diagnose or treat various medical conditions. Radiopharmaceuticals incorporate a biologically active molecule (typically a drug or a biological targeting molecule) with a radioactive isotope, creating a compound that imaging techniques can trace within the body. … Read more
