Ғылым және технология

Let's take a look at the GQ GMC-300 Geiger Counter. This video is for reference only and is not intended to take the place of the product manual or other manufacturer's documentation or recommendations.
I bought this to test for radioactivity resulting from a radioactive iodine treatment for thyroid cancer and tumors.

    Sorry to hear about your wife's diagnosis. I have an aunt and a cousin (her daughter) that both had the thyroid diagnosis. I am happy to tell you they both did very well with the treatments and are now cancer free. I tell you this to hopefully give you some comfort knowing that its definitely beatable. I wish your wife a speedy recovery and thanks for sharing with us. God bless you and your family. 73 from VE6GCM

    I'm writing this on Monday, and on Wednesday morning I'm to receive the same radioactive Iodine treatment as your wife. It encourages me to hear of her experience and recovery, as well as that of many of the commenters. I had previously noticed the GMC-300 unit in your Amazon store and felt prompted to buy a copy of it with expedited shipping. One of my biggest concerns was how to detect any residual radiation left in my "quarters" and the adjoining bathroom. This sets my mind more at ease since we will have a way to "sniff" for this residual radiation now. Thanks for the tip and the demo.

    @@SevenFortyOne Rob, I thought you'd like to know that I have my copy of the GMC-300. It's day 3 of my treatment (Friday) so I unboxed the unit (90% battery when received) and powered it up. Oddly, it sat in my lap with 0 CPM for about 5 minutes. I set up the controls and time as you suggested. Then--I peeled the plastic wrap from the front panel. Ten seconds, then the thing went nuts. 60,000 CPM! I removed the operating unit out to a table in the hallway, backed up about 6-8 feet into my room, and observed the unit--still pushing 2-3000 CPM! I will let my wife use the unit on her end of the house to monitor over there; it will be a learning experience to see the results. Then as I come out of quarantine on Monday it will be valuable to assist us in the clean-up of my quarantine room.

At first my unit started giving me random high counts up into the hundreds and then after probably a month it just continually stayed up 200+... I ended up getting a second one they're upgraded model with Wi-Fi. that one has been running over a year now and seems to be doing pretty good.
