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) | Resposta |
|---|---|
| 5-20 | Possible delayed reaction; potential chromosome damage. |
| 20-100 | Temporary Leukopenia (reduction in white blood cells). |
| 100-200 | Malaltia per radiacions lleu en poques hores: vòmits, diarrea, fatiga, reducció de la resistència a la infecció. |
| 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. Configuració
5.1 Càrrega del dispositiu
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 Engegada/apagada
- Per encendre: Press and hold the power button (usually the 'OK' button) until the screen illuminates.
- Per apagar: Manteniu premut el botó d'engegada fins que el dispositiu s'apaga.
5.3 Configuració inicial
Upon first power-on or after a reset, you may need to set the language and real-time clock.
- Selecció d'idioma: Navigate through the menu using the arrow buttons and select 'English' for the interface language.
- Configuració de l'hora: Access the system settings to adjust the real-time clock to your local time.
6. Funcionament
6.1 Mesura bàsica
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 Comprensió de la pantalla
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.
- Rellotge en temps real: Mostra la data i l'hora actuals.
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).
