WebSpecific activity is the activity per unit mass of a radionuclide and is a physical property of that radionuclide.. Activity is a quantity (for which the SI unit is the becquerel) related to radioactivity, and is defined as the number of radioactive transformations per second that occur in a particular radionuclide. The unit of activity is the becquerel (Bq), which is … WebThe simplest unit of activity is the Becquerel (Bq). A source that emits one particle per second has an activity of one Bq. Activity can also be measured in counts per minute.

A Ci is equal to 37 billion disintegrations per second. The activity of a radioactive material can be easily calculated based on the halfof the material and the mass of the material. life - Different masses of the same radioactive material have different activities. cutting board finishing oil

Webbecquerels per gram (Bq g-1). A becquerel is a very small amount of radioactivity equal to one decay per second. A square kilometer of earth, 30 cm deep, will typically contain a ton or more of uranium. In the United States today, the concentration of radioactivity in uranium ore bodies is on average about 0.3% by weight, or about 78 Bq g-1. WebMay 15, 2003 · a radioactive with a half-life of 5 days, has an initial activity of 4000 counts/min. determine the activity after 10 days. well because 1 half life is 5 days, so 10 days must be 2. so 4000/ (2^2) =1000 counts/min is that right? Yes. 2. If the initial quantitiy of radioactive material is 200gms determine the amount left after 15 days have elapsed. WebFeb 10, 2010 · In general, the number detected by a sensor must be multiplied by the ratio of a full sphere (4 pi steradians) to the solid angle subtended by the sensor, as seen by the sample. If your count per minute is the full count, simply divide by 60 to get the count per second. The becquerel is the average number of emissions per second of a ... cheap cozumel vacation packages
