Data from three experiments, held at different locations, where parent nuclei decay are shown. How do the time constants(=1/l) compare for the three experiments? Start

A source of decaying parent nuclei is placed near a detector and the number of remaining parent nuclei (blue data series) are shown (time is given in hours). Determine the time constant (=1/l). Start

A source of decaying parent nuclei is placed near a detector and both the total counts detected (black data series) and the rate of counts detected (green data series) are shown (time is given in hours). Determine the time constant. Start

An a particle is produced when a ²³²₉₀Th nucleus decays into its daughter, ²²⁸ ₈₈Ra (m= 228.03u).  What is the total kinetic energy (in MeV) of the decay products? Start
