0 the quality that some atoms have of producing a type of energy that can be very harmful to health
A dangerous amount of radioactivity was released into the environment last month.
After incubation for 4 h the precipitates were washed again, transferred to the new tubes and their radioactivity determined.
Two aspects of this alteration and the value of radioactivity to advanced life deserve attention, as detailed below.
A significant increase in the amount of radioactivity incorporated into the frozen- thawed fraction from the mixed population was evident 6 h after incubation.
The results were calculated by expressing the bound radioactivity as a percentage of the total radioactivity.
Radioactivity was found in all three intermediates - 3-ketosphingosine, dihydrosphingosine and sphingosine.
In the high altitude environment, oxygen and air density decrease, temperature and humidity are low and there is an increase in radioactivity.
Phenomena such as collisions, radioactivity and thermodynamics make for novel compositional tools via these sonification methods.
At the time stated, samples were taken for cytotoxicity assay and radioactivity determination.
