It has become popular for some people to have yearly whole-body scans (CT scans, formerly called CAT scans), using x-rays, just

to see if they detect anything suspicious. A number of medical people have recently questioned the advisability of such scans, due in part to the radiation they impart. Typically, one such scan gives a dose of 12 mSv, applied to the whole body. By contrast, a chest x-ray typically administers 0.20 mSv to only 6.0 kg of tissue. How many chest x rays would deliver the same total amount of energy to the body of a 85 kg person as one whole-body scan?

7 0

Answer:

Explanation:

Given

One CT scan gives a dose of 12 mSv

and a chest X ray typically administer 0.2 mSv to 6 kg tissue

mass of Person m=85 kg

therefore \frac{85}{6}=14.167

N no of x-Ray equals to 12 mSv dose of CT scan

n=\frac{12}{0.2}=60

Therefore total no of x ray required is =60\times 14.167=850.02\approx 850 X rays

MArishka [77]

Answer:

The wavelength in vacuum is equal to 428.8 nm.

Explanation:

Given that,

The wavelength of light, \lambda=284\ nm

The refractive index of glass, n = 1.51

We need to find the wavelength in vacuum. The relation between wavelength and refractive index is given by :

n=\dfrac{\lambda_v}{\lambda}\\\\\lambda_v=n\times \lambda\\\\\lambda_v=1.51\times 284\\\\\lambda_v=428.8\ nm

So, the wavelength in vacuum is equal to 428.8 nm.

agasfer [191]
A synthesis reaction occurs when a molecule is formed from the bonding of atoms, ions or simpler molecules. A single product is created from multiple reactants. These reactions are exothermic since they release energy in the form of light and heat.
