Maximizing distance between yourself and the patient protect you from radiation. exposure to radiation is extremely small if you are feet away from the patient.

Radiation is extensively used in the field of healthcare to treat, diagnose, and detect disease.

The examiner performing a radiation procedure on the patient should be 6 feet away from the exposure to the radiation.

Radiation exposure is a harmful event, which can lead to mutation, skin burns, and radiation sickness. The patient undergoing a radioactive treatment should be treated from 6 feet away, as it has adverse effects on the health.

For example, in the case of hyperthyroidism, the patient has been prescribed to take radioactive iodine, to treat the disease. The examiner should be 6 feet away from the patient to minimize exposure to radioactive elements or radiation.

Therefore, the examiner should be 6 feet away from the patient.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
