The becquerel (symbol Bq ) is the SI derived unit of radioactivity , defined as the activity of a quantity of radioactive material in which one nucleus decays per second
so the statement means that you have enough Cesium 137 to give you 6400000000000000 decays per second

Activity is the number of disintegrations per second, taking place inside the source.. Caesium-137 decays at the rate of 64000000000000000 second....
Hope this helps.

The activity of a Cesium atom with 137 total nucleons will produce 6,400,000,000,000,000 becquerels of energy.
Your phrase is missing an amount of mass for the Cesium.
3.7x10^10 becquerels gets you one whole Curie (Ci). This is roughly the activity of 1 gram of the radium isotope 226 Ra.
