X-Ray radiation dosage recommendation for semiconductors [RADs] devices

Hello Naphat, 

  I'm not sure what you are asking as there is not a recommended radiation exposure for devices.  We do have specific devices that are RAD-hardened for applications such as space.  You can find information on what is available here:   https://www.ti.com/sitesearch/docs/universalsearch.tsp#q=radiation&t=everything&linkId=1  .

There is also a handbook available, please review and let us know which devices your customer may be interested in: http://www.ti.com/lit/sgzy002 . 

And a Product Guide here: https://www.ti.com/lit/sg/slyt532g/slyt532g.pdf  . 

If you are looking for ICs for X-Ray equipment, here is an overview: https://www.ti.com/data-converters/integrated-special-function/medical-afes/digital-xray-afes/products.html .  

Thanks for using E2E and please let us know how we can assist further. 

Regards,
