Radioactivity and gamma rays
Some isotopes have unstable nuclei that decay and emit radiation; gamma rays are high-energy electromagnetic rays with high penetrating power.
The idea, in English
Some isotopes have unstable nuclei that decay and emit radiation; gamma rays are high-energy electromagnetic rays with high penetrating power.
Explain in Egyptian Arabic
فيه isotopes الـ nuclei بتاعتها unstable، فبتعمل decay وبتطلّع radiation. والـ gamma rays هي electromagnetic rays طاقتها عالية جدًا، وليها high penetrating power.
Common misconceptions
- Anything exposed to gamma rays becomes radioactive.
No. Gamma rays pass through the object and leave; they do not put a radioactive isotope inside it, so the object does not become radioactive. The unstable nuclei stay in the source that gives out the rays.
Explain in Egyptian Arabic
لأ، الـ gamma rays بتعدّي من الجسم وتمشي، ومش بتحط جواه radioactive isotope، فهو مش بيبقى radioactive. الـ radioactive isotope موجود في المصدر نفسه.
