Harmful Effects of Excessive Radiation
The harmful effects of the excessive dose of the ionizing radiation can be divided into two types. These are as follows:
- Deterministic effects and
- Stochastic effects
We shall discuss them one by one in detail.
Radiography: Radiation Safety
In earlier articles on radiography, you studied the effects of ionizing radiation on biological tissues. These effects can be divided into two types- Deterministic and Stochastic. Therefore, the radiation safety becomes of paramount importance white taking a radiograph.
Radiography: Radiation Physics
In this article termed as radiation physics, we shall talk about the ways, the x-rays are produced, the events that occur at atomic level during their production and how can one save oneself and others.
Production of X Rays
Electrons that travel from the filament to the tungsten convert part of their kinetic energy into x-ray photons. This phenomenon occurs by the formation of bremsstrahlung and characteristic radiation.
Radiography: Radiation Biology
Radiation Biology
Radiation biology is the study of effects of ionizing radiation on living systems. In this article we shall talk about the harmful effects of ionizing radiation on tissues, how does it occur, and how sensitive different types of cells are?
The effects of radiation on the tissues can be divided into 2 broad categories. The Deterministic and Stochastic effects.
