Answer:
Step-by-step explanation:
The statement "Men is mainly responsible for the increasing amount of radiation on the earth" is not accurate. The Earth naturally receives radiation from various sources, including the sun and cosmic rays. Human activities can contribute to certain types of radiation exposure, but the overall increase in radiation on Earth is not primarily due to human activities. Instead, it's important to differentiate between different types of radiation and their sources.
1. **Natural Radiation:** Naturally occurring radiation comes from sources like the sun, cosmic rays from space, and radioactive elements present in the Earth's crust. These sources have been emitting radiation for millions of years, and their contributions to Earth's radiation levels are significantly larger than those from human activities.
2. **Human Activities and Artificial Radiation:** While human activities can release certain types of radiation, such as electromagnetic radiation from electronic devices or medical procedures involving X-rays, these activities are generally well-regulated and do not contribute significantly to the overall increase in radiation on Earth.
3. **Nuclear Activities:** Nuclear activities, including nuclear power plants and nuclear testing, can release radioactive substances that can affect local areas. However, the global impact of these activities on Earth's radiation levels is limited.
An example of artificial radiation from human activities might be the use of X-ray machines in medical facilities. While X-rays are a form of ionizing radiation, their controlled and targeted use is essential for diagnosing and treating medical conditions. However, the increase in overall radiation levels due to such activities remains minimal in comparison to natural sources.
In summary, it's important to distinguish between various types of radiation, their sources, and their potential impacts. The increase in radiation on Earth is primarily due to natural sources such as the sun and cosmic rays, and human activities contribute only a small fraction to the overall radiation exposure.
