How do polymers interact with gamma radiation?
Homework Answers
Gamma radiations are highly penetrating radiations. It can penetrate deep into the materials. The interaction of polymers with gamma rays varies depending on the type of polymer materials employed. Some of the commonly seen effects are :
a) It can cause decoloration of the polymers. It can cause yellowish colour in plastics.
b) Since the rays are deeply penetrating it can effect the crosslinking of polymers and lead to chain scission . This leads to decrease in tensile strength and elongation.
c)The mechanical properties of polymers will be reduced.

A gamma-ray telescope intercepts a pulse of gamma radiation from a magnetar, a type of star with a spectacularly large magnetic field. The pulse lasts 0.33 s and delivers 6.0 × 10^-6 J of energy perpendicularly to the 70-m^2 surface area of the telescope's detector. The magnetar is thought to be 5.24 × 10^20 m (about 55000 light-years) from earth, and to have a radius of 8.2 × 10^3 m. Find the magnitude of the rms magnetic field of the...
