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. 

Exopsure Time for Dental Radiography

The exposer time for dental radiography is dependent upon the speed of the film whether its ‘D’ or ‘E’. The exposer time for various areas is given in the table below.

For exact data, you can see the instructions written on the inner side of the carton of the film. The modern microprocessor controlled radiography machines are coming with software that takes care of everything. You need to place the film properly, choose whether the patient is an adult or child, choose the tooth/area desired and shoot the film. You must take care of yourself and your staff for radiation protection. For radiation protection, read the article given below:
