- This device is for informational purposes and should not be used as the sole basis for critical safety decisions without professional consultation.
2.2 Understanding Radiation Dose Hazards
It is important to understand the potential effects of different radiation doses on the human body. The following table provides a general overview:
Figure 2.1: Nuclear Radiation Dose Hazards and Human Body Response. This table illustrates the potential health effects associated with various levels of radiation exposure, from delayed reactions at low doses to acute death at very high doses.
| Dose (Rum) | Odgovor |
|---|---|
| 5-20 | Possible delayed reaction; potential chromosome damage. |
| 20-100 | Temporary Leukopenia (reduction in white blood cells). |
| 100-200 | Blaga radijaciona bolest u roku od nekoliko sati: povraćanje, dijareja, umor, smanjena otpornost na infekcije. |
| 200-300 | Severe radiation sickness reaction; symptoms similar to above. This exposure is a lethal dose; 10-30% of those who die will have an LD(10-35)/30. |
| 300-400 | Severe radiation sickness; damage to bones and gut. LD(50-70)/30. |
| 400-1K | Acute, premature death. LD(60-95)/30. |
| 1K-5K | Acute death within days. LD 100/10. |

5. Podešavanje
5.1 Punjenje uređaja
Before first use, fully charge the device. Connect the provided USB-C cable to the detector's charging port and the USB-A end to a 5V power adapter (not included) or a computer's USB port. The charging indicator on the screen will show the charging status.
5.2 Uključivanje/isključivanje
- Za uključivanje: Press and hold the power button (usually the 'OK' button) until the screen illuminates.
- Za isključivanje: Pritisnite i držite dugme za napajanje dok se uređaj ne isključi.
5.3 Početne postavke
Upon first power-on or after a reset, you may need to set the language and real-time clock.
- Odabir jezika: Navigate through the menu using the arrow buttons and select 'English' for the interface language.
- Postavka vremena: Access the system settings to adjust the real-time clock to your local time.
6. Operacija
6.1 Osnovna mjerenja
Once powered on, the device will automatically begin measuring radiation levels. The main display shows the current dose rate in microSieverts per hour (uSv/h).
6.2 Razumijevanje ekrana
The high-definition LCD provides comprehensive information:
- Current Dose Rate: Displays the real-time radiation intensity (e.g., 000.00 uSv/h).
- Cumulative Dose: Shows the total accumulated radiation dose over time (e.g., 00.00 mSv).
- Average Dose Rate: The average radiation intensity over a measurement period.
- Maximum Dose Rate: The highest radiation intensity recorded during the current session.
- Sat realnog vremena: Prikazuje trenutni datum i vrijeme.
6.3 Setting Alarm Values
The device allows you to set custom alarm thresholds for both current dose rate and cumulative dose. An alarm will activate if the measured values exceed these presets.
Figure 6.1: The Fnirsi GC-01 interface for setting alarm values. Users can configure thresholds for current alarm (dose rate) and cumulative alarm, with three distinct alarm modes (sound, glitter, vibrate) available.
- Navigate to the 'Set Alarm' option in the menu.
- Use the arrow buttons to adjust the desired dose rate alarm threshold (e.g., Current Alarm 001.00 uSv/h).
- Adjust the cumulative dose alarm threshold (e.g., Cumulative Alarm 020.00 mSv).
- Potvrdite svoje postavke.
6.4 Režimi alarma
You can choose from three distinct alarm modes:
- zvuk: An audible alert.
- Vibracija: Uređaj vibrira.
- svjetlo: A visual indicator (e.g., flashing screen or LED).
These modes can be combined or used individually based on user preference and environment.
6.5 Ušteda podataka
The device automatically saves measurement data during shutdown, ensuring that cumulative dose information and settings are retained.
7. Održavanje
7.1 Čišćenje
Obrišite uređaj mekom, suhom krpom. Ne koristite abrazivna sredstva za čišćenje ili rastvarače, jer mogu oštetiti casing ili ekran.
7.2 Njega baterija
Da biste produžili vijek trajanja baterije, izbjegavajte često potpuno pražnjenje uređaja. Ako skladištite uređaj duži period, napunite bateriju do otprilike 50% i punite je svakih nekoliko mjeseci.
8. Otkrivanje problema
If you encounter issues with your Fnirsi GC-01, refer to the following common problems and solutions:
- Uređaj se ne uključuje: Provjerite je li baterija napunjena. Spojite je na izvor napajanja i pokušajte ponovo.
- Netačna očitanja: Ensure the device is not near strong electromagnetic interference. Calibrate if necessary (refer to advanced settings, if available, or contact support).
- Ekran je prazan ili zamrznut: Pokušajte s mekim resetiranjem tako što ćete duže vrijeme držati pritisnut gumb za napajanje (npr. 10-15 sekundi) dok se uređaj ponovo ne pokrene.
- Alarm se ne oglašava/ne vibrira: Check alarm settings to ensure the desired mode is enabled and volume/intensity is set appropriately.
Za uporne probleme, obratite se korisničkoj podršci.
