A miniaturized portable battery operated combined power/energy radiometer appropriate for personal use provides a convenient means for determination of the direction of maximum radiant UV power and the measurement of the total energy over time or dosage. The radiometer possesses particular usefulness for sunbathers, walkers, and other persons who are exposed to ambient radiation. Suitably the radiometer includes means for attachment to an article of clothing and/or a positionable stand.

In the method of preventing overexposure of an object located in a three dimensional field of ambient ultraviolet radiation of the range of 250 to and including 400 nanometers in wavelength in which such radiation travels toward the object from a plurality of directions, said method including the steps of monitoring ultraviolet radiation dosage by means of a ultraviolet radiation dosimeter and removing or covering said object upon attainment of predetermined exposure to prevent significant additional radiation from reaching said object, the improvement in which the step of monitoring radiation dosage includes the steps of: moving an ultraviolet radiation sensor about the space surrounding said object to determine the specific direction from which ultraviolet radiation of 250 through 400 nanometers in wavelength traveling toward said object is of a maximum intensity level; retaining said radiation sensor oriented in said specific direction for a desired interval to monitor ultraviolet radiation dosage received by said object while said object remains exposed to said radiation field; moving said ultraviolet radiation sensor about the space surrounding said object to re-determine the specific direction from which said ultraviolet radiation traveling toward said object is of a maximum intensity level after the lapse of said desired interval; retaining said radiation sensor oriented in said specific direction as redetermined to continue to monitor ultraviolet radiation dosage received thereafter by said object while said object remains exposed to said radiation field; and withdrawing said object from said ultraviolet radiation field in the event the dosage exceeds a predetermined threshold.
