AIST: IoT compatible radiation dosimeter: medical care, non-destructive inspection, space field
AIST:
point:
Check the transition of radiation amount on the spot with the main unit display or terminal
Operates for 2 years or more continuously with one button battery, and 10 years for dose measurement during radiation work
Radiation exposure can be reduced by analyzing dose data and taking countermeasures.
Social background of development:
It is almost 10 years since the accident at the Fukushima Daiichi Nuclear Power Station caused by the Great East Japan Earthquake.
It is expected that the dismantling work of the nuclear reactor will be in full swing in the future.
Radiation monitoring technology:
In the medical, non-destructive inspection, and space fields,
To reduce radiation exposure
Time transition of radiation dose during work,
Easy and highly reliable measurement,
Technology is needed.
Dosimeter developed this time:
It consists of a radiation sensor and an impact sensor.
Sensor part,
display,
LED (also used for optical communication),
buzzer,
MCU with wireless communication function,
Consists of batteries
Detects slight current changes that occur when gamma rays enter the radiation sensor.
It is an electronic dosimeter that converts the number of times into a dose.
Future plans:
The effectiveness of the newly developed radiation dosimeter is verified by applying it to the dose measurement of actual radiation work.
Considering application to medical diagnosis, non-destructive inspection, space field, etc.
