Wearable radiation detector

1. A wearable radiation detector comprising:

a radiation collection unit operable to collect light;

a memory;

a display unit operable to display an indicator;

a user input unit operable to output a user input signal corresponding to an input by a user;

an Ultraviolet Index (UVI) button operable to be activated by a user;

and

a processor operable to:

determine an instantaneous UVI value corresponding to the light collected by the radiation collection unit;

store the UVI value in the memory;

control the display unit to display the indicator based on the determined instantaneous UVI value if the UVI button is activated by the user;

select an output mode based on the user input signal received from the user input unit; and

output an output signal, wherein the output signal output by the processor is based on the selected output mode.

2. The wearable radiation detector of claim 1 , wherein the display unit includes a light emitting diode.

3. The wearable radiation detector of claim 1 , wherein the light collected by the radiation collection unit is continually collected over a period of time, and values corresponding to the light continually collected over the period of time are continually stored in the memory.

4. The wearable radiation detector of claim 1 , wherein the radiation collection unit includes a lens.

5. The wearable radiation detector of claim 1 , wherein the radiation collection unit comprises a plurality of radiation detectors, including a first detector operable to detect ultraviolet A radiation and a second detector operable to detect ultraviolet B radiation.

6. The wearable radiation detector of claim 1 , further comprising a wristband, wherein the radiation collection unit, the memory, the display unit and the processor are embedded in the wristband.

7. The wearable radiation detector of claim 1 , wherein the radiation collection unit comprises a wide band gap semiconductor.

8. The wearable radiation detector of claim 7 , wherein the wide band gap semiconductor is formed of at least one of GaN and SiC.

9. The wearable radiation detector of claim 8 , wherein the radiation collection unit further comprises a lens which focuses the light.

13. The wearable radiation, detector of claim 1 , wherein the UVI button is activated by the user via a touch screen.

14. A method of controlling a wearable radiation detector, the method comprising:

receiving light;

storing at least one value corresponding to the light received;

receiving a Ultraviolet Index (UVI) mode selection signal;

determining an instantaneous UVI value corresponding to the at least one stored value;

outputting a user input signal corresponding to an input by a user;

selecting an output mode based on the user input signal;

outputting an output signal, wherein the output signal output by the processor is based on the selected output mode; and

displaying an indication based on at least one of the output signal and the determined instantaneous UVI value.

15. The method of controlling a wearable radiation detector of claim 14 , wherein the selecting of the output mode based on the user input signal is performed via a touch screen.
