# AIRDOS04 - Specialized Cosmic Radiation Dosimeter for Airliners

![AIRDOS04](doc/img/AIRDOS04.jpg)

The upgraded version of [AIRDOS02](https://github.com/UniversalScientificTechnologies/AIRDOS02) airborne detector. The instrument is designed primarily for the dosimetry of cabin crew and flight attendants of commercial flights. A detailed description of the use is in the [user manual](https://docs.dos.ust.cz/airdos/AIRDOS04).

## Design features 

  - Rechargeable accumulators integrated with data storage in the hot-swap module called [BATDATUNIT01](https://docs.dos.ust.cz/airdos/BATDATUNIT01)

    - The changeable module allows new possible features in the future, like GNSS-based position logging with a revised module 

  - One month of continuous logging for a single accumulator charge

  - Easy measurement activation by insertion of the BATDATUNIT module

  - Data download without special software (Mass storage media)

  - Continuously incrementing time marks (Unique logging time from every measurement) 

## Where to get it?

Purchase AIRDOS04, the open-source device designed for versatility, from [Universal Scientific Technologies s.r.o.](https://www.ust.cz). For sales inquiries, contact sale@ust.cz. Developed and maintained by UST, it comes with full commercial availability and dedicated technical support. The device is released under the GPLv3 license.
