The rate of radioactive decay is expressed by the relationship: k = 0.693/t1/2 where k is the rate and t1/2is the half-life. Plugging in the half-life given in the problem: k = 0.693/1620 years =4.28 x 10-4/year Radioactive decay is afirst order rate reaction, so the expression...

rate of decay 1.At a given frequency, the rate at which the sound level in a room decreases after a source stops emitting sound; expressed in decibels per second (dB/s). 2.Of sound waves in an enclosed space, the rate at which the sound-pressure level ofreverberationdecreases; usually ...
The radioactive gases produced in these materials due to decay of Ra226 and Ra224 are also transported to indoor air through diffusion and convective flow. However, only a fraction of the radon/thoron generated in a material is able to escape to the atmosphere. The amount of activity ...
