The intensity of radiation of a radioactive substance was measured at half-year intervals. The results were: t (years) 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 1.000 0.994 0.990 0.985 0.979 0.977 0.972 0.969 0.967 0.960 0.956 0.952 where y is the relative intensity of radiation. Knowing that radioactivity decays exponentially with time: y(t) = ae-bt, estimate the radioactive half-life of the substance. ( Choose] ( Choose )
