Ambiguity in `dose_rate` units (Sv/h vs. rem/h)

[corund7266]

Hello,

I have been using the Python radiacode package with a Radiacode RC-103G device and noticed a likely ambiguity regarding the units of the dose_rate field returned by data_buf().

Setup:

• Device: RC-103G-001291
• Firmware: (4.1, May 16 2025 …), (4.14, Jul 7 2025 …)
• OS: Windows, Python 3.13
• Library: radiacode from PyPI

Observation:

• The device display / mobile app shows ~200 cps, ~5 µSv/h, hardness ≈ 2.5 (on a ^137Cs source).
• At the same moment, data_buf() items contain dose_rate ≈ 0.0005 and count_rate ≈ 190–200.
• If I interpret dose_rate as rem/h:
  0.0005 rem/h = 0.000005 Sv/h = 5 µSv/h, which matches the display perfectly.
• If I interpret dose_rate as Sv/h, then 0.0005 means 500 µSv/h, which clearly does not match the display.

Questions:

1. Are dose_rate values intentionally reported in rem/h rather than Sv/h?
2. If so, could this be clarified in the documentation / README to avoid confusion?
3. Is this behavior consistent across all device models (RC-102/103/103G) and firmware versions?

Minimal repro (Python):

from radiacode import RadiaCode
rc = RadiaCode()
for it in rc.data_buf()[-5:]:
    print("dose_rate =", it.dose_rate, " count_rate =", it.count_rate)

Best regards

Seems a subcase of issue #16 ...
