radioaktywność próbki Explanation: radioaktywność próbki materiału -------------------------------------------------- Note added at 27 mins (2019-09-16 12:49:32 GMT) -------------------------------------------------- Activity, in radioactive-decay processes, the number of disintegrations per second, or the number of unstable atomic nuclei that decay per second in a given sample. Activity is determined by counting, with the aid of radiation detectors and electronic circuits, the number of particles and photons (pulses of electromagnetic energy) ejected from a radioactive material during a convenient time interval. This experimental count, however, must be interpreted in the light of a thorough knowledge of the particular manner of radioactive decay in the sample material, because some sources emit more than one particle or photon per disintegration. - https://www.britannica.com/science/activity-radioactivity --------- The International System of Units (SI) unit of radioactive activity is the becquerel (Bq), named in honor of the scientist Henri Becquerel. One Bq is defined as one transformation (or decay or disintegration) per second. - https://en.wikipedia.org/wiki/Radioactive_decay#Units_of_rad... ------- Jednostką radioaktywności w układzie SI jest bekerel (Bq), 1 Bq = 1 rozpad na sekundę. Dawniej używaną, obecnie niezalecaną jednostką był kiur (Ci), 1 Ci = 3,7 {\displaystyle \cdot }\cdot 1010 Bq. - https://pl.wikipedia.org/wiki/Radioaktywność#Opis_ilościowy ----- In the Aliquot Activity field, type the amount of nanocuries or becquerels per unit. - https://isn.page.link/NXML |
