The proposed invention relates to an electronic ring for monitoring Vitamin D produced in a body of a user. The electronic ring comprises an Ultraviolet (UV) light sensor for determining a value of Ultraviolet B (UVB) radiation during exposure of sunlight on a body of a user. The electronic ring further comprises a microcontroller for determining an exposure time of the user to the sunlight. The microcontroller further determines an UVB dosage of the user based on a reciprocal of a product of the exposure time and a predefined weightage factor. The predefined weightage factor is associated with a wavelength of the UVB radiation. The microcontroller further determines an amount of Vitamin D produced in the body of the user based on the UVB dosage of the user.

A gauge that is configured to detect a time at which radiation enters the gauge. The gauge may include a member that is configured to transition from a first state to a second state upon receipt of the incoming radiation, and may include a light probe that is configured to detect when the member transitions to the second state. The gauge may provide for determining a time of arrival of the radiation at another gauge. For example, the gauge may correlate the time of arrival at the gauge with the another gauge, thereby providing for correlating a response time of a test specimen with actual exposure time of the test specimen to radiation (e.g., an ion beam).

A solar radiation protective band for a driver that includes a housing and an armband. The housing includes a front panel, a side panel, and a microcontroller. The front panel includes a front panel UV light sensor, a front panel IR phototransistor, and an LCD. The side panel includes a side panel UV light sensor, and a side panel IR phototransistor. A temperature sensor measures a skin temperature and generates a temperature signal. A skin color sensor detects a skin color of the driver and generates a skin color signal. The microcontroller requests an input of a SPF of a sunscreen used by the driver; calculates an exposure time threshold; generates a UV exposure warning when an exposure time exceeds the exposure time threshold; calculates an updated skin temperature; and generates an IR exposure warning when the updated skin temperature exceeds a maximum skin temperature threshold.
