Very useful for most cancer affected area like Kanyakumari district seashore
Beach sand can contain natural radioactivity from naturally occurring radioactive materials (NORMs) like uranium (238U), thorium (232Th), and potassium (40K). These materials can come from metamorphic and magmatic rocks that break down over time through weathering and erosion to form beach sand. The concentration of these materials can vary, and sands with smaller grains tend to have higher levels of activity

Seems good.
No way to tell if it's accurate. But the radiation levels do change over time. So far the radiation levels are low.

Detection
Very effective. My cat underwent radioactive iodine treatment, and I needed to protect myself. It's accurate and quick to detect. All my cat had to do was walk by or stand for any period of time. period of time.

Al parecer es un clon del FNIRSI gc-01
Parece que es un clon del equipo FNIRSI GC-01, no se le encuentra la marca original impresa en el equipo ni en el empaque, la tarjeta electrónica es diferente a la mostrada en las fotos de la página del fabricante original, la batería no corresponde a la capacidad indicada por el fabricante de 1100 mAh, internamente trae una de solo 500 mAh, no cuenta con buzzer, el elemento detector de radiación ni siquiera está en una base, solo está pegado con cinta adhesiva
