Meaning and Usage

The term "lethal radiation dose" refers to the quantity of ionizing radiation that is sufficient to cause death within a certain period of time. It is usually measured in units such as grays (Gy) or sieverts (Sv). The concept is critical in fields such as nuclear medicine, radiation therapy, and radiobiology.

The frequency of the term's use is relatively low in everyday conversation but can be frequent in technical, medical, or scientific contexts, particularly in discussions related to health, safety, and environmental effects of radiation. It is primarily used in written form within technical documentation, research papers, and safety regulations, rather than in spoken language.

Example Sentences

1. The scientists calculated that a lethal radiation dose could be harmful to anyone exposed without protection.

2. Сайентисты посчитали, что смертельная доза радиации может быть вредна для любого, кто подвергся воздействию без защиты.

3. Understanding the lethal radiation dose helps in setting safety standards for workers in nuclear facilities.

4. Понимание смертельной дозы радиации помогает устанавливать стандарты безопасности для работников на ядерных объектах.

5. Research is ongoing about the effects of a lethal radiation dose on human health and the environment.

6. Исследования продолжаются о воздействии смертельной дозы радиации на здоровье человека и окружающую среду.

Idiomatic Expressions
