An electric sign contains three flashing lights,red, yellow and green, the red light flashes on every 10 seconds, the yellow light flashes on every 15 seconds and the green light flashes on every 18 seconds. If they are switched on together, after how many seconds will they be on together again

In a cupboard at the Department of Physics you will find an old Strontium preparation 90Sr which
is 14 years old. A protocol showed that the activity was then measured at 2780 pulses / minute at a background radiation of 210 pulses / minute. The half-life of strontium 90 is 29.1 years.
How many pulses should be measured today, if the background radiation is the same now as then?

A gas filled detector has a cylindrical shape which enclose different gases and an entrance window. You are interested to detect alpha, beta and neutrons by using gas filled detectors. What modifications you will do to detect all the mentioned particles keeping in view that alpha and beta particles cannot penetrate through the entrance window of the gas filled detectors due to their short range
