Ionizing radiation in radiation theraphy isused to kill cancer cells and shrink tumours.
Correct Answer
A. True
Explanation
Ionizing radiation is commonly used in radiation therapy to treat cancer. This type of radiation has high energy and can damage the DNA of cancer cells, leading to their death. By targeting the tumor with ionizing radiation, it is possible to kill cancer cells and shrink tumors. Therefore, the statement that ionizing radiation in radiation therapy is used to kill cancer cells and shrink tumors is true.
2.
When fission occurs it produces and releases energy and neutron.
Correct Answer
A. True
Explanation
Fission is a nuclear reaction in which the nucleus of an atom splits into two smaller nuclei, releasing a large amount of energy in the process. This energy is released in the form of kinetic energy of the resulting fragments and also in the form of gamma rays and other forms of radiation. Additionally, fission also releases one or more neutrons, which can go on to cause further fission reactions in a chain reaction. Therefore, the statement that fission produces and releases energy and neutrons is true.
3.
Nuclear power has become one of the electrical energy sources.
Correct Answer
A. True
Explanation
Nuclear power has indeed become one of the electrical energy sources. Over the years, many countries have invested in nuclear power plants to generate electricity. These plants harness the energy released from nuclear reactions to produce heat, which is then converted into electrical energy. Nuclear power is known for its high energy output and low greenhouse gas emissions, making it an attractive option for meeting the increasing global energy demands and reducing reliance on fossil fuels.
4.
Nuclear is generated from atomic reaction
Correct Answer
A. True
Explanation
Nuclear energy is indeed generated from atomic reactions. This process involves the splitting (nuclear fission) or combining (nuclear fusion) of atomic nuclei, which releases a tremendous amount of energy. This energy is harnessed to produce electricity in nuclear power plants. Therefore, the statement "Nuclear is generated from atomic reaction" is true.
5.
Uranium was discovered by Martin Klaproth.
Correct Answer
A. True
Explanation
Martin Klaproth is credited with the discovery of uranium.
6.
Nuclear energy is a non-renewable energy.
Correct Answer
A. True
Explanation
Nuclear energy is considered a non-renewable energy source because it relies on the use of uranium, which is a finite resource. Once the uranium is used up, it cannot be replenished. Additionally, the process of generating nuclear energy produces radioactive waste that remains hazardous for thousands of years, making it unsustainable in the long term. Therefore, the statement that nuclear energy is a non-renewable energy source is correct.
7.
Nuclear produces electricity by boiling water into steam.
Correct Answer
A. True
Explanation
Nuclear power plants generate electricity by using heat from nuclear reactions to produce steam. This steam then drives turbines connected to generators, which ultimately produce electricity. Therefore, the statement "Nuclear produces electricity by boiling water into steam" is true.
8.
Nuclear energy can be used in the production of nitrogen fertilizer.
Correct Answer
A. True
Explanation
Nuclear energy can be used in the production of nitrogen fertilizer through a process called the Haber-Bosch process. This process uses high temperatures and pressures, which can be generated by nuclear reactors, to convert nitrogen from the air into ammonia, a key component of nitrogen fertilizer. This allows for the production of large quantities of fertilizer, which is essential for agricultural purposes. Therefore, the statement that nuclear energy can be used in the production of nitrogen fertilizer is true.
9.
Injection of radioactive isotope can be used in detecting the leaks in underground pipelines.
Correct Answer
A. True
Explanation
The injection of a radioactive isotope can indeed be used to detect leaks in underground pipelines. This is because the radioactive material can be detected using special equipment, allowing technicians to track the movement of the isotope and identify any leaks or cracks in the pipeline system. By using this method, it is possible to identify and address pipeline leaks before they become more serious issues.
10.
Medicine nuclear is used for therapeutic purposes.
Correct Answer
A. True
Explanation
Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive materials to diagnose and treat diseases. It involves the use of radioactive substances that are administered to the patient, either orally or intravenously, and then detected by special cameras or scanners. These radioactive substances can be used for therapeutic purposes, such as the treatment of certain types of cancer, by delivering targeted radiation to specific areas of the body. Therefore, the statement that "Medicine nuclear is used for therapeutic purposes" is true.
