radioactivity

It has almost no radioactivity and won’t harm the air or our pretty skies.

With calculations based on linear algebra, the research team demonstrated that -- analogous to radioactivity in atomic nuclei -- a magnetic quiver can decay into a more stable state or fission into two separate quivers.

Berkeley’s contractor, SCS Engineers, called for an inspector to walk in long, straight lines across César Chávez with a radioactivity detector.

The researchers compared the radioactivity of the sampled eastern spikes to Brazil nuts, which take up radiation from the soil in which they grow.

Although Berkeley is preparing to sweep Chávez Park with radiation detectors, there was no signage about potential radioactivity or harmful waste visible on a visit this month to the peninsula.
