17. . Radioactive tracers. Radioactive isotopes are often intro- |BIO duced into the body through the bloodstream. Their spread through the body can then be monitored by detecting the appearance of radiation in different organs. 131, a B emitter with a half-life of 8.0 d, is one such tracer. Suppose a scientist introduces a sample with an activity of 375 Bq and watches it spread to the organs.
