3-2 Mode button
To change measurement mode,
press this button. There are 3 modes of measurement,
CPM, Bq , Bq/g.
3-2-1 CPM Mode
button (gold color) pressed, AION-A7 detects radiation dose equivalent for 1
minute and displays measured data. When radiation detected, icon spins and

Measuring range: 0.06uSv ~ 500uSv / h
3-2-2 Bq Mode
In Bq mode
¡°AION-A7¡± detects energy value of natural background radiation.
User should run
this mode before measuring Bq/g mode. When the value of radiation dose
equivalent goes over 0.15uSv, lead shield case is needed to get accurate value.
When ¡°AION-A7¡± is used at home and radiation dose equivalent is over 0.2uSv,
measuring should be run in plastic or glass case. The value of natural
background radiation in
seashore or forest is usually lower than urban area.
3-2-3 Bq/g Mode
Before running Bq/g mode. Get natural background
radiation value by running Bq mode.
Value in Bq/g mode means radiation energy value from target
material such as rice, meat, fish
and so on.
Radiation dose value which is
acquired by detecting ¥ã(gamma) and ¥â(beta) particle would be
automatically converted to Bq/g value.
¡°AION-A7¡±in glass or plastic case. Then run Bq mode. It has auto power off function.
target material such as rice or fish in case with AION-A7 together.
Run Bq/g mode.If it show 0.040Bq/g value, it
means 40Bq/Kg ( 1000g x 0.040Bq/g = 40Bq/Kg).
When value of natural background radiation goes over 0.1uSv, tolerance is
If accuracy of value is needed,
measure in lead shield box.
If it detect same of
natural background radiation level.
It will show 0.025Bq/g value as
follow Japan¡¯s ministry of Health, Labour and Welfare.
For more information :
As Follow Japan government action, Under 25Bq/Kg of Bq value will display 0.025Bq/g.
It automatically calculate Bq mode of back ground radiation with Bq/g mode of value.
If user want to check raw data, Run Bq mode two times. First measurement for
Back ground radiation, Second Measurement for food's raw Bq value.
Ex ) 1Kg of Mushroom value = 35Bq , Back ground radiation = 33Bq
35Bq - 33Bq = 2 Bq/Kg.
3-3 Audio On / Off Switch.
side of ¡°AION-A7¡± is slide switch. When switch on, speaker icon appears in LCD.
When switch off, icon disappears and there would be no sound.
3-4 Battery Warning Icon.
When battery low, this icon
appears. Needs to replace battery.
<Notice> When battery low, tolerance of measured data would be
bigger than normal condition.
3-5 Auto Power off mode.
. ¡°AION - A7¡± has auto power off function. In CPM mode
and Bq mode 90 seconds after
detection finished, power would be off automatically.
In CPS mode, same
does in 10minutes. When power off automatically, only measured data in
Bq, Bq/g mode would be
4 JQA Certification (Japan Quality Association)
¡°AION - A7¡± got a JQA certification, So, AION-A7 of Factory calibration meet JQA Certification of
