How do The 100 Characters Survive Radiation? An In-Depth Look
Radiation is a constant deadly threat in the post-apocalyptic world of The 100. Nearly a century after nuclear war devastated Earth, the planet is still soaked in radiation dangerous to humans. Only those genetically engineered or sheltered from radiation have managed to survive on the hostile surface. As a sci-fi fan and data analyst, I‘m fascinated by the innovative tech and bioengineering solutions the characters use to persist in this harsh environment. Let‘s take an in-depth look at how The 100 cast manages to withstand the lingering radiation!
Nightblood: A Genetic Game Changer
The key discovery that enables radiation resistance is the bioengineered black blood known as Nightblood. This was developed on the Ark space station shortly before the bombs dropped by scientist Becca Franco, an Eligius III crew member. She created a serum that acts as gene therapy, altering a person‘s DNA to produce special proteins that can break down and metabolize radiation at a greatly accelerated rate. This prevents cell damage and radiation sickness.
When injected into the bloodstream, the serum rapidly turns the blood dark black in color. Becca used herself as a test subject, becoming the first Nightblood. The genetic modification was passed down to the Grounders descended from the initial Nightblood survivors.
According to Mount Weather records, only 1-2% of Grounders have the recessive Nightblood trait. But for them it provides a huge survival advantage. Nightbloods can absorb over 3 times more radiation than normal humans before showing symptoms. Here‘s a comparison:
| Blood Type | Lethal Dose Radiation |
|---|---|
| Normal Human | 1 Sievert |
| Nightblood | > 3 Sieverts |
No wonder the Grounders made Nightbloods their leaders! The black blood mutation conferred radiation resistance that enabled them to survive and rebuild society on the surface after Praimfaya.
The Ark survivors realize Nightblood is the key to withstanding increased radiation as reactors destabilize. Medical research leads to bone marrow transplant procedures that can confer Nightblood status and radiation tolerance to others like Clarke, Luna and Echo. Of course, the treatments come with huge risks – the first Ark test subjects didn‘t survive. But the breakthrough proves gene modification is a viable survival strategy.
Sheltering from Praimfaya
A century after the bombs fell, radiation levels have dropped enough for the Ark survivors to reach Earth. But the planet still suffers from intermittent radioactive environmental hazards. The biggest danger comes from Praimfaya – a radioactive death wave predicted to sweep across the planet as old nuclear reactors melt down.
Praimfaya turns out to be as deadly as predicted. To survive, residents of the Ark and Grounder clans use different methods to shelter from the radiation. Here are some of the key shelters:
Becca‘s Island Laboratory – With hardened infrastructure and advanced radiation shielding tech, this isolated lab rides out Praimfaya successfully.
Second Dawn Bunker – Also called Polis, this huge bunker housed 1200 Grounders locked down to shield from the death wave.
Mount Weather – The sealed underground former military base houses Skaikru survivors by leveraging its radiation filtration system.
The Ark – In orbit, the Ark astronauts boost life support systems and use water storage as shielding to protect the station from Praimfaya.
According to Monty‘s simulations, the wave of intense radiation lasted several months before dissipating. When it was over, the planet emerged into a nuclear winter. For 5 years, radiation zones prevented the survivors from leaving their shelters.
Adapting to Thrive in a Radioactive World
After Praimfaya, surface radiation levels drop to an average background level of 1-2 mSv per hour but with considerable geographic variation. That‘s enough to induce radiation poisoning in an unprotected human within months to a year. Some areas like the Dead Zone are still instantly deadly.
To monitor and adapt to these risks, Raven Reyes and Monty Green cobble together radiation detection tech from Ark salvage:
- Drones – Modified aerial drones map radiation levels and identify hotspots.
- Handheld detectors – Portable Geiger counters help characters identify radioactivity dangers.
- Badges – Individual badges monitor personal radiation exposure levels.
Other tech helps mitigate exposure. Hazmat suits, oxygen tanks and radiation meds provide protection outside shelter. Water purification systems remove radioactive isotopes. And of course Nightblood biotech proves essential for survival in this environment.
Through all these innovations, a portion of humanity manages to persist in The 100‘s harsh irradiated world. Their society has been shaped by the struggle to detect and adapt to the invisible dangers of radiation all around them. It‘s a powerful testament to human ingenuity and determination to survive against all odds. And as a science geek, I find it an inspiring example of how tech and bioengineering may one day enable humans to thrive on other irradiated worlds!
