Abstract
A dosimetry device includes a first chamber formed on a substrate with a first decomposable barrier sensitive to radiation and a first chemical component. A second chamber is formed on the substrate in proximity of the first chamber and includes a second decomposable barrier sensitive to radiation and a second chemical component. Upon a radiation event, decomposition of the first and second barriers of the first and second chambers permits a mixing of the first and second chemical components to cause a visible change of the dosimetry device.
