Definition

1. Noun:
   • Gamma: A type of electromagnetic radiation with very high frequency and energy, similar to X-rays but more penetrating. It is emitted by radioactive substances.
   • Gamma: A unit of mass equal to one millionth of a gram (1 μg).

Usage Examples

• Noun (Radiation):
  • Tia gamma có khả năng xuyên thấu mạnh. (Gamma rays have strong penetrating power.)
  • Chất phóng xạ này phát ra tia gamma. (This radioactive substance emits gamma rays.)
• Noun (Unit of mass):
  • Liều lượng được đo chính xác đến từng gam-ma. (The dosage is measured precisely to each gamma.)
  • Một gam-ma bằng một phần triệu gam. (One gamma is equal to one millionth of a gram.)

Advanced Usage

• "tia gamma": gamma ray. This is the most common compound term.
  • Liệu pháp tia gamma được sử dụng trong điều trị ung thư. (Gamma ray therapy is used in cancer treatment.)

Variants and Related Words

• Tia X (n): X-ray. A related form of electromagnetic radiation with lower energy than gamma rays.
• Microgam (n): microgram. A more common modern scientific term for the unit of mass (1 μg), synonymous with "gamma."

Synonyms

• Gamma radiation: for the ray.
• Microgram: for the unit of mass.

Notes on Usage

• In modern scientific contexts, the term "microgram" (μg) is far more common than "gamma" for the unit of mass. "Gamma" as a unit is considered somewhat archaic.
• The term "gamma" is almost exclusively used in scientific or technical discussions, particularly in physics, chemistry, and medicine.
