Yes it does require direct contact with the radiation in order to cause short term and likely long term negative effects to oneself but it is not necessary to be in direct contact with the radio active material itself.
The radiation itself is the danger, although the closer you are to the source which is producing the radiation the worse the effects will be because the radiation will be stronger the closer you get to the source which is creating and or supplying the radio activity.
So holding or touching the radio active material directly would be the worse case scenario and approaching this material in a measure of some sort would increase the damage to oneself exponentially.
What else can I help you with?
Can radiation be direct contact?
Radiation can be direct contact when a radioactive source is in direct physical contact with a person or object, leading to exposure to radiation. This type of contact can result in localized radiation dose and potential harm to the exposed individual. Proper precautions should be taken to avoid direct contact with sources of radiation.
What is the difference between conduction and radiation in terms of heat transfer?
Conduction is the transfer of heat through direct contact between objects or substances, while radiation is the transfer of heat through electromagnetic waves. Conduction requires physical contact, while radiation does not.
How many ways does heat transfer occur?
conduction - requires direct physical contact between source and sinkconvection - requires a fluid between source and sinkradiation - electromagnetic radiation from source to sink
What type of heat transfer occurs when two things are touching?
Yes, it is called transfer by conduction.Transfer by radiation requires no contact and transfer by convection requires contact through an intermediate moving fluid.
Is gravity contact to force?
Gravity requires no direct contact, if that's what you mean.
Is radation contagious?
No, radiation is not contagious. It is a form of energy that can be emitted from radioactive materials, but it does not spread from person to person like an infectious disease. Exposure to radiation can pose health risks, but it requires direct contact or proximity to a source of radiation, rather than transmission between individuals.
Does conduction require direct contact?
Yes, conduction involves the transfer of heat through direct contact between objects or substances. This transfer occurs as vibrating molecules pass their kinetic energy to neighboring molecules. Heat is transferred from the warmer to the cooler object until thermal equilibrium is reached.
What 4 ways transfer of heat energy?
conduction convection radiation direct contact
What are the different ways of heat transfer and how do they differ from each other?
There are three main ways heat can be transferred: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between objects. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves. These methods differ in how heat is transferred: conduction requires direct contact, convection involves the movement of fluids, and radiation can occur through empty space.
What are the three ways in which heat can be transferred, and how do they differ from each other?
Heat can be transferred through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between objects, convection is the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves. These methods differ in how they transfer heat - conduction requires direct contact, convection involves the movement of fluids, and radiation can transfer heat through empty space.
What is the difference between conduction and thermal radiation in terms of heat transfer?
Conduction is the transfer of heat through direct contact between objects, while thermal radiation is the transfer of heat through electromagnetic waves. Conduction requires a medium, such as a solid, liquid, or gas, while thermal radiation can occur through a vacuum.
How do radiation and conduction compare o each other?
Radiation is the transfer of heat through electromagnetic waves, while conduction is the transfer of heat through direct contact between materials. Radiation can occur even in a vacuum, whereas conduction requires a medium for heat transfer to take place. Radiation is not affected by the medium's conductivity, but conduction is dependent on the material's ability to conduct heat.
