Abstract
A disposable device for monitoring exposure to ultraviolet radiation (UVR) over a single period of time and a cumulative period of time. The device includes a base upon which is applied a UVR sensitive material that irreversibly changes after exposure to UVR. A protective covering is applied over the UVR sensitive material and includes segments that are individually removable to reveal a portion of the UVR sensitive material thereunder. A UVR exposure scale and first and second keys are provided on the base. A first segment of the covering is removed and the base is placed in an appropriate location. After a period of time, the change in the UVR sensitive material is compared to the scale and first key to determine if the level of exposure is safe for that time period. The procedure may be repeated over a number of time periods with a new segment of the protective covering being removed for each time period. The cumulative UVR exposure is determined by comparing the change in the first time period's UVR sensitive material to the scale and a second key associated therewith.
