Select such wave filter, so that the output that sensor 12 produces only represents to cause the radiation degree of erythrosis (erythroderma).As previously mentioned, this mainly is a uv b radiation.
This dosimeter also can be used as real time clock with (also can be used as alarm.In this case, the mode button can allow the user select real-time working or select adminicle work as sunbath.It also can allow the user import some suitable parameters, and these parameters are influential to the time that the user takes a solar bath safely.These parameters comprise user's skin type, the protecting factor that is coated in sunlight protective articless such as tanned lotion on user's health or emulsion and the coefficient that adds up of sunbath.
As shown in Figure 2, this dosimeter also comprises a pulse producer 19 and a microprocessor 20, and the both is by battery 21 power supplies.The output signal of these pulse producer 19 response sensors 12 and launch pulse train, its pulsed frequency and sensor 12 detected this areas cause the proportional relation of radiation intensity of erythroderma.Therefore, a quantum energy bag is represented in each pulse.
Receive by keyboard 13 input information and by sensor 12 detected this areas cause the radiation intensity of erythroderma be basis minimum erythroderma radiation dose (1MED) before, microprocessor 20 calculates can the take a solar bath estimated value of time of user.
MED is an energy density of medically distinguishing the erythrosis (erythroderma) that the people is seen.For " neutrality " skin, the limit value of this energy density approximately is a 15mJ/sg.cm.(15 milli Jiao/square centimeter).Certainly, people's skin is varied, and the sun protection product that people use is also of a great variety, and it is different that each combination of these two kinds of factors can make the people get the energy density of erythroderma.This dosimeter is by carrying out criteria classification to skin, and the colour of skin depth degree that caused taking a solar bath is in the past estimated and the protecting factor of used sunlight Protection Product is estimated and these changing factors have all been contained to come in.These information are input to dosimeter by action button 15-18 is suitably operated.
