    • 网络扩展资料

    cosmic radiation（宇宙辐射） 指来自宇宙空间的高能辐射，主要由带电粒子（如质子、电子）和电磁波组成。以下是详细解释：

    1. 定义与组成

      • 核心含义：宇宙辐射是源自地球大气层外的辐射，包括初级宇宙射线（如高能质子、原子核）和次级宇宙射线（初级射线与大气分子碰撞后产生的粒子，如介子、中子等）。
      • 能量来源：主要产生于超新星爆炸、黑洞活动等极端天体物理现象，部分来自太阳活动（如太阳耀斑）。

    2. 特点与影响

      • 高能性：粒子能量极高，可达地球实验室加速器无法达到的水平。
      • 对地球的影响：大部分被大气层吸收，但仍有少量到达地表，可能影响电子设备、生物DNA，甚至航空机组人员的辐射暴露。

    3. 相关术语

      • Cosmic radiation age（宇宙线辐射年代）：指通过宇宙射线与物质作用产生的同位素（如碳-14）来测定地质或考古样本年龄的方法。
      • 电磁辐射（electromagnetic radiation）：与宇宙辐射中的光子部分（如X射线、伽马射线）相关。

    4. 应用领域

      • 科学研究：用于研究宇宙起源、粒子物理特性等。
      • 技术影响：可能干扰卫星通信和航天器电子系统，需特殊防护设计。

    如需更深入的物理学机制或防护措施，可参考天文学或辐射防护领域的专业资料。

    网络扩展资料二

    Cosmic radiation, also known as cosmic rays, refers to the high-energy particles that originate from outside the Earth's atmosphere and bombard the Earth's surface. Here is a detailed explanation of this term.

    Definition and Usage

    Cosmic radiation refers to the radiation that comes from outer space and reaches the Earth. It is composed of high-energy particles, such as protons, alpha particles, and even heavier atomic nuclei. Cosmic radiation is constantly bombarding the Earth's atmosphere and surface, and is one of the sources of natural background radiation.

    Example Sentences

    Usage and Synonyms

    Cosmic radiation is often used in scientific and technical contexts, such as astrophysics, space exploration, and radiation protection. It is also known as cosmic rays, although this term is somewhat of a misnomer, as cosmic radiation includes particles other than just rays. Other related terms include ionizing radiation, which refers to any radiation that can remove tightly bound electrons from atoms, and non-ionizing radiation, which refers to radiation that does not have enough energy to ionize atoms but can still cause biological effects.

    Antonyms

    There is no direct antonym for cosmic radiation, as it is a specific type of radiation. However, one could refer to "terrestrial radiation" or "background radiation" to describe the radiation that originates from the Earth's surface and environment.
