Provided is an ultraviolet radiation device useful to measure intensity of the ultraviolet radiation in a selected environment which has an optical-electrical converter having an optical means for expanding an ultraviolet radiation input angle of the converter, a temperature sensor and an electrical signal conditioner having means to generate an ultraviolet intensity signal which is independent of ambient temperature. A preferred device is for personal use and permits allocation of measured daily doses of solar ultraviolet radiation over multiple days to provide a predetermined total cumulative amount of ultraviolet radiation and a desired tanning of skin during sunbathing. The preferred device issues a signal when the daily allocated dose is reached. The invention also provides by using the device of the invention a process to determine prevailing ultraviolet radiation levels and cumulative amounts and a controlled process for tanning.
