Description

Voice cognition personal dosimeter

The present invention relates to a voice recognition personal dosimeter which attaches a voice recognition transducer to a personal dosimeter which is a radiation personal safety device and informs the exposure dose by voice through an earphone.

Conventional radiation safety equipment is worn inside the upper pocket of protective clothing to prevent contamination of the individual exposure dosimeter worn when entering and leaving the contaminated work area. It must be checked every time and the work must be suspended and checked each time even in the presence of spatial radiation dose rates in general industrial sites.

Looking at the use of radiation safety equipment in a conventional radiation workplace with reference to Figure 1 as follows.

1) The radiation worker should bring the radiation safety equipment described in the radiation work permit.

At this time, check the calibration and reactivity test date (6 months validity period) of radiation safety equipment.

2) If the indication of the dosimeter exceeds 10% of the measuring range, replace it with an appropriate one.

3) The personal exposure dosimeter should be worn inside the upper pocket of the protective clothing to prevent contamination from radioactive material. If necessary, it should be put in a thin plastic bag and packed in one layer with masking tape.

4) In case of wearing shielded clothing, dosimeter should be worn in shielded clothing.

5) When using the dosimeter, put it into the work area in the radiation area, taking care not to pollute it with the contact of gloves.

6) After completion of the work, record the dose in the daily exposure log.

7) Enter the management area, take off the protective clothing in the reverse order, and complete the work if there is no problem after contamination inspection.

8) Even if work is being carried out, if the indicated allowable dose is exceeded or is likely to be exceeded, immediately exit the radiation area.

The use of such conventional radiation personal safety equipment has not been able to properly utilize the radiation personal safety equipment in the protective clothing in the place where the air pollution by the radioactive material, etc. and there was an inefficient problem in the field using the radioisotope.

It is an object of the present invention to improve the work efficiency by receiving radiation doses by voice when the radiation worker is sequentially put on the radiation work wearing a protective suit, and if there is a concern that the limit dose is exceeded or approached, the immediate release from the radiation workplace It is to provide a voice recognition personal dosimeter that prevents exceeding the limit dose in advance.

The voice recognition personal dosimeter of the present invention is equipped with a voice recognition transducer in the personal dosimeter which is one of the safety equipment to improve the work efficiency by receiving the exposure dose by voice through the earphones sequentially during the radiation work. If there is a risk of exceeding or approaching the limit dose, it should be possible to leave the radiation workplace immediately.

The voice recognition personal dosimeter of the present invention is equipped with a voice recognition transducer in the personal dosimeter. Therefore, when the exposure dose in proportion to the generation of the electrical signal generated by radiation, etc. exceeds + 10mRem, it is configured to be transmitted to the radiation worker voice through the earphone.

The configuration of the present invention will be described in detail with reference to FIG.

2 shows a configuration of a voice recognition personal dosimeter according to the present invention, wherein a Geiger Muller tube 2 is installed inside the main body 1 and the dose value measured by the Geiger Muller tube 2 is measured by an amplifier 3. Is sent.

The amplifier 3 sends the amplified value to the pulse height selector 4 and the pulse height selector 4 selects only usable pulses and sends them to the counter 5. The exposure dose measured by the counter 5 is displayed on the LCD instrument panel installed outside the main body.

The counter 5 operates the LED diode 6 to blink the LED lamp 7 when the measured exposure dose is larger than the set exposure dose, and generates an alarm sound through the speaker 8.

On the other hand, the counter 5 operates the voice recognition converter 10 so that a voice signal sends a warning message to the wearer through the earphone connection terminal 11.

The power for operating the voice recognition personal dosimeter of the present invention is supplied by the battery case 12 and the high voltage power source 13 installed in the main body 1.

Reference numeral 14 shown in the drawings is a watch.

The measuring principle of the voice recognition personal dosimeter of the present invention is to amplify the amount of electricity generated by the GM TUBE (2) with the amplifier (3) and then pulse the required pulse. The radiation dose is converted into the radiation dose by the counter 5 by selecting the separator 4.

Thus, the radiation dose converted by the counter 5 is converted into a voice signal by the voice recognition converter 10 and transmitted to the radiation worker through the earphone.

The voice recognition personal dosimeter of the present invention prevents radioactive workers from entering or exiting the worker's body through the respiratory system or the skin of a radiation worker who enters and exits in an air-contaminated area due to radioactive material. To ensure that voice workers use voice recognition when wearing appropriate protective clothing and masks, or where radioactive isotopes exist in industrial sites (non-destructive testing institutions, research institutes, universities, hospitals, etc.) By immediately recognizing the radiation dose, radiation safety management can be performed more effectively.
