How Do You Spell STRONTIUM-90?

Pronunciation: [stɹˈɒnti͡əm nˈa͡ɪnti] (IPA)

Strontium-90 is a radioactive isotope that is commonly used in nuclear waste and cancer treatments. The spelling of this word can be explained using IPA phonetic transcription as /ˈstrɒn.ti.əm-ˈnaɪn.ti/. The first syllable "stron" is pronounced with a short "o" sound followed by a "n" sound, while "tium" is pronounced with a long "i" sound. The second part, "90", is simply pronounced as "nine-tee". Overall, the phonetic transcription helps to clarify the proper pronunciation of this complex scientific term.

STRONTIUM-90 Meaning and Definition

  1. Strontium-90 is a radioactive isotope of the chemical element strontium, denoted by the symbol Sr-90. It is produced as a result of nuclear fission or fusion reactions that occur in nuclear reactors, as well as during nuclear weapons explosions. This isotope possesses a half-life of approximately 29 years, meaning that half of the original quantity of Sr-90 will decay radioactively in that time frame.

    Due to its radioactive nature, Strontium-90 emits beta particles, which are high-energy electrons, during its decay process. These beta particles can be harmful to living organisms if ingested, inhaled, or absorbed into bodily tissues. Specifically, strontium-90 has a chemical behavior similar to calcium, allowing it to accumulate within bones and teeth. This can lead to health risks, as the radiation emitted during its decay can cause cellular damage and subsequent health issues, including an increased risk of cancer and other adverse side effects.

    Strontium-90 is monitored and regulated by various international organizations and governments due to its potential health hazards. Regular measurements are taken to assess its presence in the environment, such as air, soil, water, and food sources, in order to ensure levels remain within acceptable safety limits. The cleanup and management of strontium-90 contamination around nuclear facilities or affected areas is crucial to protect public health and mitigate the impact of this radioactive isotope.

Etymology of STRONTIUM-90

The word "strontium" is derived from the name of the village Strontian in Scotland, where strontium minerals were first discovered. The element was named by the Scottish chemist Sir Thomas Charles Hope in 1790.

The number "90" in "strontium-90" refers to the isotope of strontium with a mass number of 90. The number simply denotes the total number of protons and neutrons in the atomic nucleus of the isotope.
