Chapter 399: Sunshine is Also a Disaster
Gu Pan and Lu Ruisheng didn’t quite understand, so they looked towards Chen Shaonan, hoping to hear his explanation.
Chen Shaonan said to them, "The intensity of ultraviolet rays is divided into five levels: very weak, weak, moderate, strong, and very strong. Level 1 has an index of 0-2, Level 2 has an index of 3-4, Level 3 has an index of 5-6, Level 4 has an index of 7-9, and Level 5 has an index of 10 and above. If it’s more than 10, it can be very harmful to humans."
After saying this, Chen Shaonan paused, then continued, "Low-level ultraviolet radiation exposure can cause erythema, swelling, and pain to the skin. However, if the wavelength of UVA reaches the dermis and stimulates melanin particles, it will lead to blisters, peeling, pigmentation, and other issues. And if it gets more serious, it can lead to basal cell carcinoma, malignant melanoma, and other types of skin tumors."
The mention of malignant tumors made everyone inhale sharply because this was no longer about superficial wounds; it was life-threatening. Cancer was hard to treat before the apocalypse, and now without medicine, wasn’t this just waiting for death?"
Seeing the look of horror on everyone’s faces, Chen Shaonan still went on, "Every natural environment will become much more dangerous after the apocalypse. So, if there are extremely strong ultraviolet rays, I dare not predict what will happen. But I can say, it would definitely be fatal."
This wasn’t to scare people; it was to keep everyone vigilant.
After understanding the explanation, Gu Pan suddenly felt her gear wasn’t sufficient. Although she wore a broad-brimmed hat over her helmet, which looked a bit funny, she still felt it wasn’t enough. She asked Chen Shaonan, "Teacher Chen, what are the countermeasures?"
Chen Shaonan shook his head, "It’s not severe yet. We must hurry to the base camp. It’s best to wait it out there or figure out some effective methods before hitting the road again. Speaking of which, I’m not a professional." He indeed wasn’t a professional, so he dared not recklessly give suggestions.
