Energy Dosage for UV Irradiation in Microorganisms
The table below illustrates the amount of UV energy needed (at a radiation of 253.7nm) to inhibit microorganism growth and to completely destroy the presence of the microorganism.
| Organisms (English Scientific Term) | Type | Disease | Energy dosage of Ultraviolet radiation needed for kill factor (µW/cm2) |
| Bacillus snbths spores | Germ | 22,000 | |
| Bacteriophage | Virus | 6,600 | |
| Coxsackie yinus | Virus | The bowel way infects | 6,300 |
| Shigella spores | Germ | Germ dysentery | 4,200 |
| Escherichia coli | Germ | Food poisoning | 6,600 |
| Fecal coliform | Germ | The bowel way infects | 6,600 |
| Hepatitis A virus | Virus | Hepatitis | 8,000 |
| Influenza virus | Virus | Influenza | 6,600 |
| Legionella pneumopila | Germ | Army corps germ disease | 12,300 |
| Salmonella typhi | Germ | Typhoid | 7,000 |
| Staphylococcus aureus | Germ | Food poisoning, poisoned shock and Comprehensive disease, etc | 6,600 |
| Streptococcus spores | Germ | Throat infection | 3,800 |
According to known standards for disinfection, different microorganisms will have a different killing and death quality value when using UV-C. It can be calculated using the formula as below.
K (disinfectant quantity- μ W Sec/cm2) = I(the strength μ W/cm 2)* t(time-sec)
Based on this formula, it can be seen that either a high strength, short time or a low strength, long time will provide similar disinfection effects.
However, in reality, there are many factors to consider when calculating the amount of UV energy required, including air flow, humidity levels, time and distance, making the calculation very difficult. Although this is so, studies have shown that sufficient UV light is able to kill any microorganism containing DNA and that the UV light effects are additive.
