radiation resistance
C1technical/scientific
Definition
Meaning
The property of a material or organism to withstand damage from exposure to radiation.
1. In physics/engineering: The ability of materials to maintain structural and functional integrity under radiation exposure. 2. In biology/medicine: The ability of cells, organisms, or tissues to survive radiation exposure, often due to genetic or cellular mechanisms. 3. In electronics: The ability of components to operate correctly in radioactive environments without failure.
Linguistics
Semantic Notes
Almost exclusively used in scientific, engineering, medical, or technical contexts. Rarely used figuratively. Typically functions as a compound noun (radiation + resistance), though occasionally appears hyphenated ('radiation-resistance') in adjectival form.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning. British English may occasionally hyphenate more frequently ('radiation-resistance testing'), while American English tends toward open compounds ('radiation resistance testing').
Connotations
Equally neutral and technical in both varieties.
Frequency
Equally low frequency in general English but equally common in relevant technical fields in both varieties.

Examples
By Part of Speech
verb
British English
- The polymer was engineered to radiation-resist extreme conditions.
- Materials are tested to see how they radiation-resist.
American English
- The alloy was designed to radiation resist in space.
- We need components that can effectively radiation resist.
adverb
British English
- The device performed radiation-resistantly throughout the test.
- The material degraded less radiation-resistantly than expected.
American English
- The component failed to function radiation resistantly.
- It reacted more radiation resistantly under vacuum.
adjective
British English
- They developed a radiation-resistant coating for the satellite.
- The radiation-resistance properties were carefully documented.
American English
- The spacecraft requires radiation-resistant electronics.
- The study focused on radiation resistance characteristics.
Examples
By CEFR Level
- The satellite needs materials with good radiation resistance.
- Scientists test the radiation resistance of different metals.
- The development of electronics with high radiation resistance is critical for space exploration.
- Radiation resistance in certain bacteria could provide clues for cancer treatment.
- The polymer composite exhibited exceptional radiation resistance, maintaining its tensile strength after exposure to 50 kGy.
- Genetic modifications in Deinococcus radiodurans confer its extraordinary radiation resistance, making it a model organism for radiobiology studies.
Learning
Memory Aids
Mnemonic
Imagine a RADIO (radiation) trying to play music but a strong wall (RESISTANCE) blocks its signals, keeping the area safe.
Conceptual Metaphor
SHIELD metaphor: Radiation resistance is conceptualised as an invisible shield protecting an object from harmful rays.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'resistance' as 'сопротивление' in the electrical sense; it's 'устойчивость' or 'стойкость'.
- Do not confuse with 'radiation-resistant' (adjective) which is 'радиационно-стойкий'.
Common Mistakes
- Using 'radiation resistance' to describe blocking radio waves (that's 'RF shielding').
- Confusing it with 'heat resistance' or 'corrosion resistance'.
- Incorrectly pluralising ('radiations resistance').

FAQ
Frequently Asked Questions
No. 'Radiation resistance' describes a degree of tolerance or ability to withstand damage, implying some effect may still occur. 'Radiation-proof' suggests complete imperviousness, which is rarely achievable.
Yes. In biology and medicine, it describes the ability of cells, microorganisms (like certain bacteria), plants, or animals to survive exposure to ionising radiation.
Radiation resistance specifically concerns protection from high-energy particles and electromagnetic waves (e.g., gamma rays, X-rays). Thermal resistance concerns protection from heat transfer (conduction, convection, radiation in the infrared spectrum).
No. It is a specialised technical term. English learners should only learn it if they are studying or working in relevant scientific, engineering, or medical fields.
