1. What is UV-C Dose Calculation?

UV-C dose calculation determines the total energy delivered per unit area during ultraviolet germicidal irradiation. It's essential for ensuring effective disinfection while maintaining safety standards.

2. How Does the Calculator Work?

The calculator uses the UV-C dose formula:

Where:

• \( Dose \) — Total energy delivered (mJ/cm²)
• \( Intensity \) — UV-C irradiance (mW/cm²)
• \( Time \) — Exposure duration (seconds)

Explanation: This formula calculates the cumulative UV-C energy exposure, which directly correlates with microbial inactivation effectiveness.

3. Importance of UV-C Dose Calculation

Details: Accurate dose calculation is crucial for effective disinfection protocols, ensuring pathogen inactivation while preventing material degradation from overexposure.

4. Using the Calculator

Tips: Enter UV-C intensity in mW/cm² and exposure time in seconds. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical UV-C dose for disinfection?
A: Typical doses range from 10-50 mJ/cm² for most pathogens, though some resistant microorganisms may require higher doses.

Q2: How is UV-C intensity measured?
A: UV-C intensity is measured using calibrated radiometers or spectroradiometers specifically designed for the UV-C wavelength range (200-280 nm).

Q3: Does distance affect UV-C dose?
A: Yes, intensity follows the inverse square law with distance from the source. Dose calculations should account for the specific distance used.

Q4: Are there safety considerations for UV-C exposure?
A: Yes, UV-C can cause skin and eye damage. Proper protective equipment and safety protocols must be followed during UV-C applications.

Q5: Can this calculator be used for all UV-C applications?
A: This calculator provides basic dose calculation. Complex applications may require additional factors like reflection, absorption, and shadowing effects.
