Abstract
A system (5) for quantifying a colour change in a colorimetric indicator (15), the system (5) comprises an image capture device (22) configured to acquire an image of an object (10) comprising the colorimetric indicator (15); and a processing device (20) configured to compare the acquired image to reference data (30) associated with the colourimetric indicator (15), and generate a quantitative output (28) associated with the acquired image.

Abstract
A UV radiation (UVR) response indicator comprises a first UVB and/or UVA radiation sensitive material which has been modified so as to display an altered characteristic in a delayed manner in response to UVB and/or UVA radiation exposure. The UV indicator is capable of displaying exposure to increased UV radiation over a period of time. The present invention also relates to a method of displaying a relative amount of exposure to UVR by a UV indicator over a period of time. The invention is particularly useful in detecting the level of exposure to sunlight or sunbed radiation.
