Answer:

Uses of ALPHA PARTICLES:

• Alpha particles emitted from the radio isotopes are used as projectiles for nuclear reaction. The scattering of alpha particles from the nucleus helps us in estimating the size of the nucleus and in understanding the nature of nuclear forces.
• Alpha radiation is used to treat various forms of cancer. This process, called unsealed source radiotherapy, involves inserting tiny amounts of radium-226 into cancerous masses. The alpha particles destroy cancer cells but lack the penetrating ability to damage the surrounding healthy cells. Radium-226 has mostly been replaced by Safer, more effective radiation sources, such as cobalt-60.
• Alpha radiation is used in some smoke detectors. The alpha particles from americium-241 bombard air molecules, knocking electrons free. These electrons are then used to create an electrical current. Smoke particles disrupt this current, triggering an alarm.

Uses of BETA PARTICLES:

• Knowing the penetrating power of the Beta Radiations emitted from the radio isotopes, they are used to control the thickness of paper, plastic and metal sheets during their manufacture.
• In a process known as brachytherapy, beta radioisotopes can be used to irradiate areas inside a patient to prevent the growth of certain tissues. This approach has been used successfully to prevent the clogging of arterial inserts called stents. Beta particles are also used in some forms of therapy to kill cancer cells. In addition, the emission of beta particles is used indirectly in the medical scanning technique known as positron emission tomography (PET).
• The salts of weak radioactive isotopes such as Radio-Sodium Chloride, Radio-Iron, Radio-Iodine are used for diagnosis. Such radio isotopes are called the TRACERS. These tracers are used to detect the suspected Brain Tumours and Blood Clots before they become dangerous. The tracers are also used to study the natural process in the human body. For Example: Radio-Sodium Chloride is injected with common NaCl in the human body and the radioactivity of the blood at different parts of the body is tested to study the blood circulation. This process is called RADIO-CARDIOLOGY.

Uses of GAMMA RAYS:

• Many diseases such as leukemia, cancer etc. are cured by radio therapy. Gamma Radiations obtained from Cobalt-60  are used to treat cancer by killing the cells in the malignant tumour of the patient.
• Gamma rays emitted by the radio isotopes are used to sterilize bandages, dressings, syringes and other equipments to make them free of germs. This method is quicker, more reliable and cheaper than the process of sterilization by heat.
• Gamma rays are used in an industrial setting to detect defects in metal castings and to find weak spots in welded structures. In a process known as industrial radiography, sections of structures are bombarded with gamma rays which safely pass through the metal. The metal is then observed by portable gamma cameras which show a darkening of the weak points in the structure on a photographic image. Gamma rays are also used to examine airport luggage and cargo.
