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:  

  1. Deterministic effects and   
  2. Stochastic effects  

 We shall discuss them one by one in detail.

Radiography: Effects of Radiation on Oral Tissues 

Dentists often encounter cancer patients, who are to undergo radiotherapy or have received it in the recent past. Besides cancer therapy, these patients need dental treatment for different ailments. Therefore, it becomes paramount important for a dentist to know the effects of large doses of ionizing radiation on oral mucosa.

In this section, we shall talk about the effects of radiation on oral tissues.

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.

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.   (more…)
