Optical fibre can be safely used for signal transmission near the nuclear installation because ___________

(a) There is no leakage of signals

(b) Plastic cladded silica fibres are resistant to nuclear radiations

(c) Plastic cladded silica fibres are not resistant to nuclear radiations

(d) There is no electromagnetic interference

The question was posed to me at a job interview.

My question is based upon Functional Materials in chapter Materials and their Properties of Engineering Chemistry I

Right option is (b) Plastic cladded silica fibres are resistant to nuclear radiations

For explanation I would say: Optical fibre can be safely used for signal transmission near the nuclear installation because the plastic cladded silica fibres are resistant to nuclear radiation. Due to total internal reflection, light can be transmitted over many kilometers without any appreciable decrease in the intensity of optical fibres.
