Described is a self-indicating instant radiation dosimeter (1001) for monitoring high energy radiations, such as X-ray. The dosimeter contains a radiation sensitive, color changing, indicating composition (10), e.g., a diacetylene (RCCCCR, where R and R are substituents groups) or a radiochromic dye, a polymeric binder (20) and optionally a shelf life extender (50) or an activator (40). The radiation sensitive composition (10) changes color instantly when exposed to high energy radiation. The dose is estimated by comparing the color with a color reference chart or more accurately with a spectrophotometer or an optical densitometer. The radiation sensitive composition (10) is protected from low energy radiation such as UV light, by a layer of low energy absorbing materials, such as UV absorbers.

The present invention relates to a head and neck simulation phantom device for simulating the head and neck of a body, the phantom device including: a flat type first plate having a first insertion groove formed on one surface thereof; a flat type second plate disposed to come into contact with the other surface of the first plate and having a second insertion groove formed on the contacted surface with the other surface of the first plate in such a manner as to correspond to the first insertion groove;

and a plurality of teeth simulants inserted into the first insertion groove and the second insertion groove and for simulating the teeth of the body.
