Sieverte

Sieverte is not a widely recognized term in scientific references. The correct term in physics and radioprotection is sievert, symbol Sv, the SI unit used to quantify the biological effect of ionizing radiation. The unit is named after the Swedish physicist Rolf Maximilian Sievert.

In practice, sieverte may appear as a misspelling or typographical error for sievert in texts. It can also arise as a proper noun in fiction or as a surname in some languages, but there is no standard scientific meaning attached to the form sieverte.

The sievert measures dose equivalents and effective dose. It is a derived unit defined in relation to the absorbed dose and weighting factors that reflect the biological impact of different radiation types and the varying sensitivities of tissues. In particular, equivalent dose H_T equals the absorbed dose D_T multiplied by a radiation weighting factor w_R for each tissue, and the effective dose E is the sum of those tissue-weighted values over all tissues. Doses are commonly expressed in millisieverts (mSv) in clinical and occupational settings, with higher values indicating greater potential health risk.

All usage of the term sievert in official contexts refers to the same unit; any instance of sieverte should be treated as either a misspelling or a nonstandard usage unless clearly defined in a specific work.
