Definition

Noun: A collection of symptoms and health effects resulting from exposure to ionizing radiation. The severity and type of symptoms depend on the dose of radiation received, ranging from nausea and hair loss at lower doses to organ failure, cancer, and rapid death at very high doses.

Usage

The term "radiation syndrome" is used to describe the acute and chronic medical conditions caused by radiation exposure. * The doctors diagnosed the patient with radiation syndrome after the nuclear accident. * Understanding the stages of radiation syndrome is critical for emergency response planning.

Advanced Usage
  • Acute Radiation Syndrome (ARS): This is the formal medical term for the collection of health effects that appear within 24 hours of exposure to high doses of ionizing radiation over a short period.
    • The firefighters were treated for Acute Radiation Syndrome.
  • The condition is often discussed in the context of dose-dependent effects, meaning different symptoms appear at different radiation dose thresholds.
Variants and Related Words
  • Radiation Sickness: A more common, non-technical synonym for radiation syndrome, especially the acute form.
    • The early symptoms of radiation sickness include nausea and fatigue.
  • Acute Radiation Syndrome (ARS): The specific clinical term for the immediate illness following high-dose exposure.
Synonyms
  • Radiation sickness
  • Acute Radiation Syndrome (ARS)
Notes on Meaning

"Radiation syndrome" specifically refers to the harmful biological effects of ionizing radiation (e.g., from radioactive materials, X-rays, nuclear reactions). It does not refer to effects from non-ionizing radiation like visible light or radio waves. The progression of the syndrome is typically categorized into stages: prodromal (early symptoms like nausea), latent (a period with few symptoms), and manifest illness (where severe, specific symptoms appear based on the systems affected).

Noun
  1. syndrome resulting from exposure to ionizing radiation (e.g., exposure to radioactive chemicals or to nuclear explosions); low doses cause diarrhea and nausea and vomiting and sometimes loss of hair; greater exposure can cause sterility and cataracts and some forms of cancer and other diseases; severe exposure can cause death within hours
    • he was suffering from radiation
