Summary

Story summary

The Institute of Science Tokyo, led by Yasuto Narukiyo, has developed a Wi-Fi receiver that can operate in nuclear reactors.
The receiver withstands radiation doses up to 500 kilograys, far higher than typical electronics.
Tests before and after radiation exposure show only a slight decrease in gain.
Narukiyo plans to improve the receiver and develop a two-way transmitter with a design that minimizes PMOS transistors to boost durability.
