Which of the following is/are correct regarding the radioactive wastes...
• Statement 2 is incorrect: Ionizing radiation takes a few forms: Alpha, beta, and neutron particles, and gamma and X-rays.
• Statement 3 is incorrect: Radioactive waste produces three types of radiation i.e. alpha, beta and gamma rays. Gamma rays are the strongest rays and can be blocked only through thick concrete.
Radioactive Wastes
• Radioactive wastes are the wastes emanating from a nuclear power plant or medical laboratory. They contain the radioactive materials that are hazardous to most forms of life and the environment. The wastes decay over the course of time, so they would be confined to a safe place until the time they lose their radioactivity and no longer pose a threat to the environment. The time specified earlier depends on the type of waste and radioactive isotopes. Effects of radioactive pollutants depend upon halflife of the matter, energy releasing capacity and rate of diffusion. Lower the half-life, higher will be the rate of radiation. Energy releasing capacity and rate of diffusion directly increases rate of radiation.
• All types are caused by unstable atoms, which have either an excess of energy or mass (or both). In order to reach a stable state, they must release that extra energy or mass in the form of radiation. Herein, gamma rays are the strongest rays and can be blocked only through thick concrete. Alpha rays are very weak and can be easily blocked by a piece of paper.
• Most radioactive waste comes from nuclear electricity production and military activities. However, it is also generated in hospitals from the use of radioactive material to diagnose and treat the sick and sterilize medical products, in universities in conducting vital research in biology, chemistry and engineering, and in agriculture, where nuclear applications have helped produce crops that are more drought and disease resistant, as well as crops with shorter growing periods or increased yield – a practice that has been especially beneficial for some developing countries.
• Statement 3 is incorrect: Radioactive waste produces three types of radiation i.e. alpha, beta and gamma rays. Gamma rays are the strongest rays and can be blocked only through thick concrete.

Most Upvoted Answer
Which of the following is/are correct regarding the radioactive wastes...
Effects of Radioactive Pollutants
- The effects of radioactive pollutants depend upon various factors such as the half-life of the matter, energy releasing capacity, and rate of diffusion.
- A shorter half-life means the substance will decay faster, releasing radiation more quickly.
- The energy releasing capacity determines the intensity of radiation emitted.
- The rate of diffusion determines how far the radiation can spread and affect living organisms.
Types of Radiation
- Radioactive waste produces three types of radiation: alpha, beta, and gamma rays.
- Alpha rays consist of two protons and two neutrons and are the weakest type of radiation.
- Beta rays are high-energy, high-speed electrons or positrons.
- Gamma rays are the most penetrating and dangerous type of radiation.
Blocking Alpha Rays
- Alpha rays are actually the weakest type of radiation and can be easily blocked by a piece of paper or even human skin.
- The statement that alpha rays are the strongest rays and can only be blocked by thick concrete is incorrect.
- It is important to use the appropriate shielding material based on the type and energy of radiation emitted.
