Understanding the Impact of Ultra-High Energy Particles on Biological Systems
Ultra-high energy particles from outer space create Extended Air Showers (EAS) when interacting with Earth's atmosphere, leading to the formation of dense cores emitting radiation. These particles can affect biological organisms, memory storage, and health risks, with implications for medical research and data protection.

EAS impact on biological systems By: DmitriyBeznosko Nazarbayev University Astana, KZ
What is EAS A particle with ultra-high energy arrives from outer space and enters atmosphere In interactions, billions of secondary particles are born They form two parts: Core 1-2 meters wide central area, very dense Extended Air Shower (EAS) disk of up to few km Time, ns Distance from core, m Observation level with detectors
EAS Core EAS Core is very dense with very energetic hadronic (those found in a nucleus) particles Together, they give lots of radiation to any object they hit Error-correcting code memory (ECC memory) for computers was invented to correct errors mostly from cosmic rays small storage cells can flip their value with cosmic rays passage If core passes massive data failure. Can affect Hard drives too in a same way. CREDO as monitor of risk areas. Particle density vs. distance from EAS axis (primary is proton with energy of 1017 eV) https://www.makeuseof.com/tag/data -corruption-prevent/
EAS and life Primordial Earth before life Separate cosmic rays can only break molecules, not create In EAS core very high dose, many breaks new combinations, new molecules. Origin of life? https://www.space.com/32644-cosmic-rays.html
EAS and Health risks EAS radiation. Core can deposit high dose in human parts (hands, legs, whole body) that can cause different disease (leukemia, cancer, etc...) If primary energy very big (>1019 eV) and a person is caught standing up in the core, can receive lethal dose (few Sv) Ultra-high energy cosmic rays are VERY rare one a year per km2. Core is few meters wide. In a densely populated city, probability is rising. Global monitoring (CREDO) and correlation between high energy events and medical database can uncover these correlations, provide doctors information on EAS https://scienceaid.net/Space_Radiation
