The Shocking Truth Behind Polonium-204 Poisoning in Netflix’s Kate Movie Revealed!

by

In the vein of pulse-pounding action films such as John Wick and Kill Bill, the Netflix film Kate offers an exhilarating journey filled with suspense. Starring Mary Elizabeth Winstead as the titular character Kate, an assassin who is desperately trying to uncover the culprits who administered a lethal dose of Polonium-204 before it claims her life, this movie is a thrilling roller coaster ride. Winstead’s performance is complemented by Woody Harrelson as Varrick, Kate’s handler, and Tadanobu Asano (Shogun) portraying Renji, a yakuza boss.

Although I’m no chemistry whiz (I might have missed a few lectures), it’s clear that Polonium is a formidable element – at least, that was my understanding before seeing the movie Kate. To my surprise, Polonium-204 is indeed a genuine chemical element, and it’s incredibly toxic. However, the way the film depicts how this substance influences the character played by Winstead seems to stray from scientific reality.

What Polonium-204 Is In Netflix’s Kate

A Stranger Poisons Kate With Polonium 204 At A Hotel

Following a past assassination that left her disoriented, Kate is on the brink of embarking on her last assignment prior to leaving the dangerous world behind. One evening, she encounters a stranger at a hotel bar, and they end up finishing a bottle of wine together before spending the night together. The following day, Kate attempts to eliminate her latest target but suddenly feels lightheaded and misses her target instead.

Subsequently, she meets with a car accident and is admitted to the hospital. The doctor there informs her that she suffered radiation poisoning by consuming Polonium-204, and she has merely 24 hours left to live. Upon realizing that it was the hotel guest who had poisoned her, Kate embarks on a quest for answers.

In her relentless pursuit of the culprit, Kate battles one thug after another, all while the effects of polonium gradually weaken her body. Along the way, she encounters a troublesome yet captivating teenager named Ani, who proves to be one of the most memorable characters in the film Kate. To combat the poisoning, Kate administers frequent doses of a stimulant to maintain her strength, but as the story progresses, her condition deteriorates, leading to symptoms such as nosebleeds, dizziness, vomiting, and agonizing pain. In the end, after exacting her revenge, Kate acknowledges her impending demise when the movie concludes.

Yes, Polonium-204 Is A Real Poison — What It Is, Explained

Polonium-204 Can’t Be Used To Poison Someone

Polonium-204 is indeed an authentic chemical element, but it’s quite intricate. This element was discovered by the renowned physicist Marie Curie and her husband Pierre in 1898. Polonium belongs to the chalcogen family with an atomic number of 84 and a weight of around 209.

More notably, its most common form is Polonium-210, which can serve as a lethal toxin, as demonstrated in the tragic case of Alexander Litvinenko. A Russian spy who settled in the UK, Litvinenko was intentionally exposed to Polonium-210 in 2006.

The signs of Polonium-210 exposure encompass feelings of nausea and vomiting, hair loss, and damage to bone marrow. In substantial amounts, it may impact the central nervous system, leading to seizures, confusion, and causing the victim to fall into a coma within minutes (as reported by Medical News Today)). However, in the movie Kate, while Kate experiences vomiting, her on-screen symptoms such as nosebleeds, dizziness, and other physical manifestations are fictionalized for dramatic effect.

In contrast to Polonium-201, Polonium-204 isn’t a practical method for poisoning someone in reality due to three main reasons. Professor Ron B. Davis, who hosts the YouTube channel “ChemSurvival,” explains these reasons:

Firstly, Polonium-204 has a half-life of just 3 ½ hours, making it useless after a day as it decays and loses its potency.
Secondly, transferring Polonium-204 from one person to another is risky due to the high radiation it emits, potentially affecting the transporter.
Thirdly, creating significant amounts of Polonium-204 requires neutrons with a short half-life, making it impractical for large-scale production.

As of now, there’s no known real-life instance of Polonium-214 poisoning to validate the symptoms portrayed in the movie Kate, which could be due to the fact that employing this element as a poison is extremely challenging, if not impossible. It remains unclear why the creators of Kate opted for Polonium-214 as their chosen poison; they may have done so because they didn’t anticipate the scrutiny of chemistry experts or simply aimed to craft an exciting action movie.
