Summary Introduction

To determine:

The way through which radiation is used to treat cancer.

Introduction:

The energy emitted spontaneously from the nucleus of an atom is termed as “nuclear radiation”. Nuclear radiation has many forms that were discovered are, “alpha particles, X-rays, gamma rays and beta particles or positron”. They can be high energy rays or high–energy particles.

There are some radioisotopes with short half-lives can be used in nuclear medicine. Some specific radioisotopes can use to get images of specific body tissues. These types of useful radioisotopes are prepared in laboratory. Two types of medical radioisotopes are as follows:

(1). In diagnostic states of disease

(2). In therapeutically treating diseased tissues
