You can spell it out as you did or you can simply write "2".
You would write it as "2 hours"
It is +2
There is no need to write the leading 0s. So just 2 will suffice.
To calculate the dose for a 55 kg patient, you would multiply the patient's weight (55 kg) by the recommended dosage (4.2 microcuries/kg). This gives you a dose of 231 microcuries for the patient. To convert microcuries to millicuries, divide by 1,000. Therefore, a 55 kg patient should be given 0.231 millicuries of I-131 for the test.
The M43A1 detector contains a small amount of radioactive material typically in the form of a sealed radioactive source, such as cesium-137 or americium-241. This radioactive material is used to generate radiation for detection purposes in the detector.

The curie (Ci) is a unit of radioactivity, not specific to uranium. However, for uranium-238, which is the most common isotope of uranium, the activity typically ranges from 0.1 to 0.3 microcuries (µCi) per gram. It's important to note that radiation levels can vary depending on the specific isotopes present and their concentrations.

The LD50 (lethal dose for 50% of test subjects) of strontium-90 is not precisely established in humans due to ethical reasons. However, animal studies suggest a range of LD50 values depending on the route of exposure (oral, inhalation, etc.) and health of the animals. Generally, strontium-90 is considered a high-risk radioactive substance with potentially lethal effects at relatively low doses.
Write 5' 2" or 5 feet 2 inches.
You could write 2 1/2 or 2.5.
This is how you write an equivalent fraction:2/4=1/2
you can you can only write it as 2/3
