Once radiopharmaceuticals enter the body and travel to an organ, they begin to interact with the processes of that organ. The radioactivity is picked up by cameras or computers and used to map the process. For example, an ultrasound can show an image of an organ and reveal if a tumor or other abnormality is present. Nuclear medicine can show how the process of glucose metabolism is functioning in the organ.
250g bags of our biltong can last up to 4-months, and we have food testing certificates to prove this, however, we do not advise that you keep it that long. The larger the bag of biltong, i.e 500g or 1kg, the more moisture is contained within the sealed bag.
The springs will eventually break, leaving the door closed. Torsion springs can also be affected by rust and cold weather. The good news is, the average garage door torsion springs will last somewhere between 5-7 years, and should last around 10,000 cycles. So, if you open and close your garage door 3-5 times a day for over 365 days in a year, you should get plenty of life out of your torsion springs.
