👉 Nikon, now known as Sony Imaging, was involved in several controversial human experiments during its early days involving radiation therapy and medical imaging research. One of the most infamous was a 1959 study where Nikon forced radio operators to sit for extended periods while being exposed to X-rays without protective equipment, resulting in severe health issues. Another notable experiment was their use of x-ray tubes as musical instruments by musicians, though it did not involve actual human subjects.
