## Abstract

A smart dosimeter coupled to a legal dosimeter and used as if they were incorporated into one structure. A sensor, provided in the smart dosimeter, detects a worker is wearing the legal dosimeter. An instantaneous exposed dose value can be checked, in real time, to assist a worker with performing an operation or task. A motion detection unit detects a motion; a legal dosimeter detection unit checks whether the legal dosimeter is coupled to the smart dosimeter; a wearing check unit checks whether the worker is wearing the legal dosimeter based upon motion information; a G-M detection unit detects a real-time exposed dose of the worker; and a data communication unit transmits the exposed dose, detected by the G-M detection unit, to a management server and receives warning situation information from the management server.

### Claim 2 (depends on 1)

The smart dosimeter according to claim 1, further comprising:
an alarm unit for outputting a sound to the outside to provide an alarm sound to the worker when the real-time exposed dose detected by the G-M detection unit is higher than a preset reference exposed dose, or when the warning situation information or warning and usage restrictions are displayed on the LCD display unit.

### Claim 3 (depends on 1)

The smart dosimeter according to claim 1, wherein a legal dosimeter detection unit comprises a sensor which comprises a proximity sensor, an infrared sensor, a pressure sensor, a detection sensor, or a near filed communication means, including an RFID.

### Claim 4 (depends on 1)

The smart dosimeter according to claim 1, wherein a coupling part comprises an insertion groove formed on one side of the smart dosimeter, and an adapter of the legal dosimeter is inserted into the insertion groove such that the legal dosimeter is coupled and fixed to the smart dosimeter.

### Claim 5 (depends on 1)

The smart dosimeter according to claim 1, wherein, when the legal dosimeter is fixed, the smart dosimeter recognizes, through a legal dosimeter detection unit formed in the fixed position of the legal dosimeter, that the legal dosimeter is coupled to the smart dosimeter.

### Claim 6 (depends on 1)

The smart dosimeter according to claim 1, wherein a coupling part comprises a legal dosimeter insertion pocket configured, on one side of the smart dosimeter, and the legal dosimeter is inserted into an inner hole of the insertion pocket and then the insertion pocket is inserted into the smart dosimeter and fixed therein, and
the coupling part is configured such that the insertion pocket is inserted into or popped out of the smart dosimeter when an upper portion of the insertion pocket is pressed.

### Claim 7 (depends on 6)

The smart dosimeter according to claim 6, wherein the coupling part further comprises a driving unit to move and position the insertion pocket inside or outside the smart dosimeter according to a selection of an external button or a switch.

### Claim 8 (depends on 6)

The smart dosimeter according to claim 6, wherein the coupling part comprises:
a fixing part for supporting and fixing the insertion pocket;
a switch for controlling whether to fix or release the fixing part by a pushing force exerted from outside; and
an elastic part for pushing the insertion pocket out of the smart dosimeter from an inserted state using an elastic force.

### Claim 9

A smart dosimeter for coupling of a legal dosimeter, the smart dosimeter comprising:
a motion detection unit for detecting a motion of the smart dosimeter;
a legal dosimeter detection unit for checking whether the legal dosimeter is coupled and fixed to a coupling part included in the smart dosimeter;
