To determine which among alpha and beta particles has higher ionizing power, we can follow these steps:Step 1: Define Alpha and Beta Particles - Alpha Particle: An alpha particle is essentially a helium nucleus
The power exchanged between the electrons and the microwaves is amplified and displayed on the y-axis of the oscilloscope. (Adapted from Swallow.)The early stage radiolysis reactions in dry biological powders and crystals have been identified by electron paramagnetic resonance (EPR). Electrons possess...
It can be utilised for reading dosimeter films used for individual protection of people who can be subjected to ionising radiations, e.g. in nuclear power stations, fuel treatment, space flights.
ARCHER Belfast HISTORICAL CONSIDERATIONS The discovery of X-rays by Roentgen in 1895 and radium by Curie, three years later, furnished the medical profes sion at the tum of the century with a novel diagnostic tech nique and therapeutic method of unparalleled versatility and power. Never...

Beta radiation can be completely stopped by approximately 1.0 cm perspex. Each isotope produces a spectrum of energies but has characteristic maximum energy that determines its penetrating power and the distance of the radioactive “field” around it. Typically a β particle has a range of 4m in...
