Naphthalene is an aromatic hydrocarbon found in coal tar or crude oil. Naphthalene is used in the manufacture of plastics, resins, fuels, and dyes. It is also used as a fumigant insecticide that works by turning directly from a solid into a toxic vapor. This process is called sublimation.
Scintillation detectors are used to detect all types of radiation, including γ-rays, electrons, neutrons, α-particles, and neutrinos. ... For example, detection of light particles such as photons requires the material to have high effective atomic weight and high density.
Naphthalene is also used in paints and in the production of the insecticide carbaryl, used in home yards and gardens. Still predominant in the exposure of consumers worldwide is the production and use of crystalline (pure) naphthalene as a moth repellent and disinfectant.
